...some users have quotes/phrases under their screennames/avatars when they post messages but some users (including myself) say "opening" under them? I can't figure out how to change it!
Once you reach 3000 posts, you gain the ability to change your title (the text below your account name).
Yes but please do not spam (i.e. make pointless posts) to get those 1000 posts, as that will most certainly be frowned upon.
And as I mentioned in a previous thread, we can alter your post counts, so excessive posting to reach 1000 will result in your post count going back to zero, or if we're really feeling mean, we can set it to a negative number
