"Bump" means that someone replied to a thread so it would "bump/move" it back to the top of the page. Sometimes threads get lost waaaay down there. The red "X" means a link or icon did not work. Sometimes, this is because we leave out numbers or letters, so it just doesn't post right. Sometimes, sites no longer use them, so they are no longer available. Does this make sense??? (BTW, not dumb questions.) Hope I helped a wee bit!
