Usually, on most boards, there are congratulations threads for people who reach a certain post count. On this board, there will be two times that creating such a thread should be encouraged, or what have you:

-when a member reaches 500 posts (anyone can start the thread).
-when a member reaches 1000 posts (if this ever happens).

The person who gets to 1000 posts will be made a banner. Just a small thing - they can choose what they want in it; if it's pictures, please provide links - that will go into a thread. Kinda like most boards. Might also try to come up with another bonus, but we shall see.

Oh, and those who reach 1000 posts will, as per the rules, get to pick their own custom title.
