Correct answers so far:
2. Spring (from the J2Stuff polls)
3. Mystic Legend's first level of Queen of Board was so large you could not save your game properly.
5. Dethman, in the "first to post and..." thread.
6. Whoever guessed Brian is simply amazing.

7. JCS.ref was the name of the site
8. Alienator had a relatively large (for the board at that time) altercation with the administration about creating a comedy forum; he insisted one was necessary, and continued to advocate its creation after the incident. Thus, the best answer is Comedy Cafe.
9. Jazz2Stuff
10. Miscellaneous Stuff, in his thread "Miscellaneous Enough."
11. Jazz3City

12. Pepper Spray was my original answer, but Electroblaster is ok too.
13. *it*
14. Bilsy


That leaves 1, 4, and 15 unanswered. Unless my memory fails me, nobody has answered 1 correctly; this was in the days of the JMMB where everybody but special members had the rank "Member" or "Junior Member." Although Dethman did post something similar at the very end of the JMMB, I am thinking of a very long post titled "____'s Manifesto" written by a member not yet mentioned. 15 is quite obscure, though, as a hint, I'll mention it has something to do with question 13.
