As suggested by @GettinBetter over in another thread, I've now added a few (optional) extra fields to the thread creation page for all model forums.
Now when creating a post, you'll see them at the bottom:
Which if filled in, will then show above the main post text, like so ...
The reason I haven't made them compulsory is that would get annoying really fast if posting about something irrelevant to those fields.
Hopefully this, combined with the new alert to stop people posting issues in the newbie lounge will help organise things a bit better, and cut the need for "which model is this?" posts
