These message boards can be configured to grant different posting titles when your account reaches a certain number of posts.
Title 1 - 0 posts
Title 2 - 10 posts
Title 3 - 100 post
and so on.
I thought it might be fun to offer you members the chance to come up with ideas for the titles. If we decide to use the titles that you've suggested, you will be rewarded with your own custom title that is unique to you.
