Hi Soccorgirl,
I'm new to the board too, WELCOME!! I pretty sure it's just to move your topic back to the top of forum. Makes it more noticable!! Talk to ya later.
that is exactly what it does...
sometimes things move sooo fast that someone's post doesnt have enough time to be seen before it gets lost down the list but if it gets bumped back up..it has a greater chance of getting noticed....
Bump?? 
I have seen it as a couple of responses. Thanks.
