Aha, yes. I actually used the Nodus client, which comes with an XRay feature among other small things, but I didn't intend to use it to harm other players or the server. I have since removed the entire client mod, though I would like to use Rei's minimap mod to make getting around easier.
A month seems like quite a long time! I feel like I'd lose interest in the server by then, honestly.
I appreciate the feedback though!
