This is the wiki for the J programming language.
You can create an account on the wiki. This lets you set preferences, and is a prerequisite for editing the wiki. When you create an account, you should use the same email address that is subscribed to the programming forum, so that we can be sure this is a valid account.
You must login in order to make changes. Note that after you login, you may need to refresh a page in order for the Edit link to appear instead of Immutable Page.
