/invite (name)
I think it would be cool if we could could invite people from another server, so they could join the one their friend is in. This would be pretty useful with friends. Say my friend is in a betting server and I don't know it, he types /invite SuperROBO1 and a pop up on my screen shows who invited me, and the servers name, giving me an option to accept or decline.
To prevent spam, there would be a 1 min time limit between invites, and also, and option on the top right of the invite to "not except from this person again".
So, how about it guys?
