Forum Mailing Lists
There are four forum mailing lists:
programming - - the main forum, covering J programming from beginner to expert, and announcements
beta - current beta (bugs, problems, suggestions)
chat - all other discussions on computer languages and J - messages welcomed from both J and non-J programmers
general - installation, support, website and other infrastructure topics
Serious J users should subscribe to at least the programming forum, and the other forums depending on your level of interest.
To decide which forum to post to:
- if the message is specific to the current beta, then the beta forum
- if the message is in some way related to programming in J, i.e. "How do I solve problem x in J?", then the programming forum. Such messages should be short and contain some J sentences or an explicit request for help in using the J system. Announcements should also be posted to programming.
- if the message is related in some way to J, but on a topic of interest to a wider community, then the chat forum
- if the message concerns installation, support, wiki/website, or other J-specific topic, then the general forum
Please avoid off-topic posts to these forums, and reply to the right forum if a post is misplaced. Cross-posting is discouraged.
Etiquette
The programming, beta, and general forums are core forums. Posting messages to the core forums is restricted to active J users. Anyone is welcome to read these forums, but please do not send a message unless it is relevant to your J learning or programming.
The chat forum is an open discussion group, covering computer languages as long as there is some connection to J: array programming, aspects of other computer languages, historical tidbits, random questions about J, wish lists, etc. You don't need to be a J programmer to post to chat, and we welcome messages from outside the J community.
Many people will see your message. It is basic courtesy to take the time to compose carefully and be as concise and clear as possible.
In answering questions, remember that teaching fishing is better than giving a fish. Rather than 'this is how' say 'these docs show you how'.
Moderation
The core forums are moderated and posters of inappropriate messages will be directed to chat.
Jsoftware will remove any member that, in Jsoftware's sole opinion, sends messages that are abusive or inappropriate to the purpose of the forum.
Subscribe
To subscribe, follow the above links to the Forum Mailing List pages and enter your email address and password in the Subscribing to ... section. An email will be sent to you to confirm the subscription.
You can set options after you have subscribed.
The email address you use to post to the forum must be enrolled in the mailing list. Posts from email addresses that are not subscribed are discarded. If you only want to post from a given address, subscribe it, then alter it to not receive traffic. If you change your email address, you need to update your forum subscription.
Subscriber email addresses are kept confidential from other subscribers, and are only visible after posting an email to a forum.
Options/Unsubscribe
Follow the above links to the Forum Mailing List pages, and click the "Unsubscribe or edit options" button at the bottom of the page.
Archives
The above links to the Forum Mailing List pages also point to the forum archives.
The archives can be searched here.
See also Archives.
Bounces
Some messages sent to the forums are not accepted, and instead simply discarded.
If you sent a message and it does not appear in your forum inbox, first check whether the message was accepted by going to Forum Search and pressing the Search button. This shows the last 100 messages on the forum, and is updated every 5 minutes.
If your message was not accepted, the most likely causes are:
It was sent from an email address not subscribed to the forum. Most often this is because the member has more than one email address and posts with an address not subscribed. However, sometimes the member's email administrators change the format of an email address without notifying the member, and the message bounces even though the member is posting from the usual email account.
Whatever the reason, forum posts are only accepted from a subscribed email address. Note that you can subscribe more than one email address, and mark all but one as not receiving forum posts - this enables you to post from more than one email address.The message size was larger than 100KB, usually because of an attachment.
In general, we discourage attachments as causing too many problems with email. A better alternative is to make files available somewhere on the web and link to them in the email. The J wiki can be used for this. If necessary, create an account on the wiki and upload your files to your wiki home page, or a subdirectory of that, see Owned Pages.
Formats
The mailing lists send out emails in plain text format. For best results, please send messages to the forum in this format.
When copying J session output to an email, first set box-drawing characters to Ascii. In J6, this can be done using menu Tools|Toggle Ascii Box Drawing.
Gmail
If you post a message from a gmail account, it will not show in your gmail inbox, even though the message is properly delivered to, and distributed by, the mailing list. This is a gmail feature - gmail recognizes it already has a copy of the message and does not show it again.

The Mailman archives preserve message threads, so if you reply to a post, it will maintain the original thread, even if you change the subject.
If you want to start a new thread, create a new message, rather than reply to an earlier post.
