Good for you for asking!
When a thread/question doesn't get responses for a while, it will fall to the 4th or 5th pages etc. Before too long, it goes off into oblivion and lost forever. Often the 'search function' doesn't work well, so folks will give the thread a 'bump' back to the first page, to give folks who haven't seen the thread, an opportunity to view or respond to it. Many authors of the thread will go back and respond again to get their thread going again.....or they may merely type 'bump' to get it back to the top of page one....
Now, if someone wants to help me figure out a Glitter signature...I'd be much obliged...

I can't even figure out how to get my hometown on here....much less a fancy avatar.
