Hey Skirata, just a heads up,
There are many people playing this game with....less than honorable intensions. They may want to try to join just to cause your guild problems, or whatever else is going through their evil little minds. Having a guild code out in public allows anyone to join whenever, you may never know who's
really joining. IMO it's not really the best idea to give the public that kind of advantage.
I speak from experience when I say that Guild Code+Wrong Hands=BAD news
Just giving ya the heads up on this.
Best of luck mate!
