When we "bump" we put this back into the "active column" in forums. the active column, my discussions, unanswered, all change as people make comments. This "bump" sorta brings it back to the top of the active column so more will notice and hopefully join. it took me awhile to even know that i could click on the word "my discussions" and see all my discussions i have had since joining.( The same with active and unanswered too) sorry but i am a novice at computers and especially chatting on one, this is the only site that i talk to friends. hope i explained it good.
