Ok. I need help with class names for my server. The server's name is RoboCraft.

Current Names:

Piston

Diamond

Emerald

Bedrock

Elite

Ultra

Titan

I was wondering if anyone had ideas. I was hoping for names that have to do with something mechanical. This server is going to get bigger so don't pass it up!

ip; robocraft.hopto.org

If you leave your IGN and join the server if I pick the names you give me I'll give you Admin or something special!
