Both Gamesville and Spigo are currently looking for assistance! Spigo needs some new admins, and you can reply on their facebook page. Be sure to include your Spigo username!
Gamesville has two spots open right now. They need a flash developer and a backend developer. I have idea what either of those things are, but if you do and you want to join an awesome team, you can apply here. ^_^ If the link confuses you, just remember that Lycos is the parent company of Gamesville.
As for Free2WinGames, well, I’m not exactly hiring, as that would imply I have money to spend. *^_^* But if you’re at all interested in helping out, there’s a new link in the menu bar titled “Opportunities.” Check it out!
