Ticket Guidelines Plugin
This is an external plugin. Please don't report any tickets here. See below for more information.
This plugin adds your project's ticket guidelines to the ticket view. This way a reporter immediately knowns (some of) the rules for filing a new ticket. These guidelines are specified in by wiki pages TicketGuidelines/NewTicketSummary and TicketGuidelines/ModifyTicketSummary. The former is displayed on new tickets, the latter on already existing tickets. Both guidelines should only be a summary of your ticket guidelines to avoid overloading the ticket form.

The author is no longer developing the plugin, but a revised version of the plugin can be found on GitHub. That is likely to become the official version, pending a reply from the author.
