Neo,
This is a good idea that, of course would require more work for you.
Maybe a dropdown for OS, there may be too many. How about a blank field that is required before posting. Just like you have for the Subject title on new messages.
Also maybe for uname -a output and possibly for User level of expertise as a background.
OS Type: ________________
Output of uname -a: ______________
User LVL of expertise: noob, beginner, basic, regular, advanced, expert, adept, master
