If you expect the players to take the server seriously, then don't interfere with their gameplay. I'm not going to view this project again. I saw your reply to the visitor playing your server, if he decides to PK, with a char he has struggled to lvl up, is it your task to kill him then? You abused your position by summoning on the player to your position then summoning a demon to kill him, this is bad publicity.
Can't been that much hard work put into the project if the project leader himself is a little immature kidd. Honestly, I think the project will die.
Seriously, all I saw in this custom made client was a broom stick. Get serious or don't advertise at all, I feel sorry for people wasting their time on servers like this one, when they are to be abused later on by one of the head managers.
