Should mean "back to topic" and actually only one person is giving such interesting input to the discussions. And that sometimes to about ten discussions at the same time. Sounds like a teacher to me!
It means "back to the top" as Sebastian correctly pointed out and it was meant to push the old topics which TRS-Romania dragged up with always the same message back to the bottom of the topic list. The serious discussion board is not the playground for a feud between two users, so I tried to bring back the topics of more general interest.
ah, thanks. Having an 11year old text messager at home is like trying to decipher secret code. Thank God for queenzone.com in keeping me hip to the new lingo!
