Sounds like a great idea!
Additionally, the first few minutes after a new player logs onto Gemp-Lotr can be the most important as to whether they want to consider staying. If they feel overwhelmed, or are not welcomed with open arms, especially if they are shy, they may just give up right away. So if there was a way (some indicator next to their name perhaps) that we could tell if someone in the Main Lobby had never played a game on Gemp-Lotr before, the rest of us could make sure that new player feels welcomed (e.g. offers to help them with navigating the site, or invites them to a friendly game, etc.) right off the bat. Things like that can go a long way.
