Thing is, most of the functionality is there, for LS commands, all they have to do is comment out a few checks a la

if (lsLeader.Pos == lsMember.Pos)
kick(lsMember);
(yes, it's a very simplified example)

and it would already make people happy - for now.

Additional features like the LS message would only involve adding a command which sets a message to show in LS_CHAT_COLOR to players. There is already a server message displayed on logon, so all they would have to do is show the message depending on LS membership, that shouldn't be too hard either.

The "bonus" things like a GUI can wait, commands would already be enough
