Good ideas and suggestions!! The most common approach is as Griatch suggested, a simple "fill in the blank" Support Request Template. I moved the current SRT to the announcement section of the Gimp Help forum so it will always be the first thing a member sees when browsing that section.
There are many technical and security issues one would face in creating a template that automatically inserts a post into a phpBB forum. phpBB is designed in such a way as to make auto-posting a non-trivial venture, with permissions that must be checked, data validity checks, along with multiple databases that would need to be updated correctly. Also, once implemented, it would be somewhat of a hassle to maintain when new updates to phpBB came along.
Even the designers of phpBB chose not to auto-post their SRT. Their solution was to create a SRT that wasn't integrated with phpBB but instead, ran outside of phpBB. The user would still be responsible for registering, and copy & pasting the results of the SRT into a new thread in the forums.
Y'all can take a look at what they did here...
