I don't put up many messages cause I am only 16 and just like to listen to other people mostly. I looked in the archives but couldn't find anything there to explain it. Maybe they left when Xenite. Org moved, or maybe they've been busy, or maybe they haven't thought of anything to post. I don't know.

Galadriel has reappeared after a long absence. Perhaps, like you, they read the messages and decide that they have nothing to contribute to the discussion. Then again, they may be on secret mission for the Council. I don't put up many messages cause I am only 16 and just like to listen to other people mostly.
