This is the list for JSPWiki developers and contributors, and anyone who is interested in the current state and development. For example, all bug reports and enhancement requests from JIRA are automatically sent here. The jspwiki-dev list is hosted at Apache, so you join by sending an email to email@example.com. The list archives are also browseable.
If you subscribe to this list you will get emailed when (a committer) commits new or changed files to the SVN repository. The jspwiki-commits list is hosted at Apache, join it by sending an email to firstname.lastname@example.org. Again, the list archives are also browseable.
Unsubscribing is equally easy: you can just send an email to <user|dev|commits>-email@example.com from the same email address that you originally subscribed from.
