I realized that FAQ does not provide the information about the basic titles in the forum. So here's the info about the forum titles I've found so far, just in case of anyone who was wondering about them, especially me. D: Please correct me if I was wrong, thanks.

= Basic Titles (still working on it) =
0 - 9 : Newbie
10 - 29 : Warming Up
30 - 49 : Green Marine
50 - 99 : Mini-Member
100 - 249 : Junior Member
250 - 666 : Member
667 - 999 : Forum Regular
1000 - 2499 : Senior Member
2500 - 3999 : Forum Staple
4000 - 5499 : Forum Legend
5500 - 6999 : Forum Spammer
7000 - 19999 : Why don't I have a custom title by now?!
20000 - ??? : Seriously?! What do I have to do to get a custom title around here?

= For particular post counts =
* 0 : Registered Lurker
* 1 : Registered just to make one post
* 50 : Pistol Start * 69 : Nice Member
* 206 : Bony Member * 420 : Dank Marine
* 666 : Evil Member
* 911 : Forgotten Member

= For particular reasons =
* Did something really stupid : Loser
* Did something even more and more stupid : Banned
* Did something extraordinary remarkable, regardless of good or bad, Or you've just won the event : "custom title"

I wonder if there are more unique titles for particular thread counts.
