In order to have a nice community and good understanding between guild members, all of you need to follow the next rules :

[1] All guild members should speak only English in guild-chat. It doesn't matter you have a friend in guild, you can simply whisper him / her. Breaking this, can go to a demote !

[2]All guild members should use their professions / mats / armors / weapons in order to help other guild members. Besides that, NEVER ask for e price between guild members, you help becouse you want, not to earn more gold. Breaking this isn't going to demote you, but it could promote you sometime !

[3]NEVER use PUGs ! Since we're a PvE-guild, we need to ensure that our members aren't Locked with some PUGs for instances. All guild members will raid all instances in one week ( until resets ), so no one needs to worry about not getting his items / emblems. This is the most important rule, so, if someone break this, he / she will be kicked from guild as soon we notice his ID's.

In time, maybe more rules will appear, so try to keep an eye on this section !
