Wow, this will be for JVS, which is the mod I'm working on. Which means that everyone should have it if they're playing a JVS server. I'll probably put some check in to make sure people can't join a JVS server unless they have the mod. So, I'm not really concerned with making sure everyone has the callback. I just want to know to remove one row item from the drop down.
P.S. Don't call me a noob, lol.
