I bet that this is caused by people finding out about Caphori through another site and going "That sounds awesome I'll go check it out!" They then do not read about the password and jump straight to trying to connect to the IP. They then go "Well that's gay! How am I supposed to join!". I know that's what I did before finding out that Caphori had a forum to get the password from.
This is just an idea. If it is no way possible then say so please.
It's not really a problem, you just the occasional "x left." in the chat. They give up pretty quick.
I know that I just wanted everyone to know so they could stop wondering. Other than that some of the names get lots of lols, such as "Terraria Left" which in that case everyone goes "Oh no! That's impossible!".
figured as much, and yeah, alot of them are lols. I laugh most when familiar names show up because it means they're having some issues XD.
