I think you should make it apparent that we cannot change our names when joining this server, perhaps in the tutorial.

Me and my partner joined a few days, unaware that we could not change our names. Now we cannot get on for 30 days and are going to have to look for another server, shame because we really liked this one.

It was a good job we hadn't bought the VIP+ packages yet! We were just about to buy them!

I enjoyed the few days we had, it will be sad to leave so soon.
