I'd rather the site was called something obvious, like "gamerdex.com". Noob isn't only a gaming term. Seeing it doesn't instantly make me think gaming.

Too bad, I've been hoping someone would come along and drive Confluence out of where I work. It is an "enterprise wiki", which is to say it adds tons of features that get in the way of work, but that management likes. It takes days of emails just to get all the permissions changed to allow someone to see a page you wrote.
