Be warned. If you conform to the rules of this guild they will still kick you out for suggesting the rules could be better. It happened to me.
I was asked to remove trade offers that some members felt did not comply with their 'fair trade' rules. I complied with that request. However when I stated that I felt the guild's trading rules were flawed I was kicked out.
So sticking by their rules isn't enough for this guild, you also have to keep your mouth shut if you disagree with them.
Needless to say, I am now looking for a new guild - preferably one with few or no trade restrictions.
