If you go out for op just to have a few extra commands, you will get rejected.
It's kind of pointless becoming a crafter so that the chances of becoming an op are better, since ops are dedicated to keeping the server clean and in working order, and not building.
Becoming a crafter is like the top builder you can be, then giving it all away?
If it's for the commands, then like spartan said you will get rejected.
We do it to help the server, not the blue name.
