*pings thread to test something*
Hmm, I guess I can't trigger a new thread posting on my own...but if that 'Last Post' thing points you to the first post in a thread to occur after you last looked at a particular thread, then yes. But say I goto the game forums and the title's bold, then when I open that thread there is a 'View First Thread' link that jumps you to the first thread that posted since you last opened that thread.
