TinyNinja gets my vote for UoF. I like the fact that he tries to keep things lively and is respectful to others in the zone. He works well with others too.
I don't know about AoL. I haven't spent a lot of time there. However, I hear really good things about Cupido. So I guess Cupido gets my vote for AoL.
RIP my Lamby. I love you.
