okay since the past few weeks people been spamming our server randomly nonstop so we decided to take one step further and just to happen one my friend saw SexyCo which requires Invitation code/pass which our server find very interesting but which also non of us know how to set this up, basically asking for a guide/tut. plus this would help other who needs it as well.
I hope everyone who knows about this info please set forward and help us, thank you very much.
