Don't be an ass but don't take yourself too seriously either! Common sense reigns supreme Mutual respect not only for your guild but also the community at large is a must.
Remember, carry yourself well in game from how you name your character (names referencing pop culture or that are vulgar/offensive in nature will be denied membership, again, common sense) to how you chat and present yourself to the community as a whole while wearing the Vanquish guild tag.
You represent something more then just yourself now, do us proud and remember YOU are the face of the guild.
Whining in chat or vent. I have my very own definition of whining - "Complaining about something over and over again to the same people and those people can do nothing about it."
Be the source of drama. I know tifts and disappointment will happen, we are human after all but should you go out of your way to cause drama within the guild you will be warned twice then removed.
Ask to be removed, or go inactive without notice. Hey, we are not for everyone and thats ok! If you ask to be removed from the guild I will do so and do so respectfully as we shake hands and part ways as friends who see things differently. Also, should you go MIA on us for a period of 30 days+ WITHOUT a heads up as to why, you will be removed from the guild. Due to GW2's roster cap of 100 members we will be adamant about this. Remember, removal due to inactivity is far from being BOOTED from the guild, your re-invite is ready when you are should you make a return!
Making an ass of yourself and in turn the guild. You are the face of Vanquish, your actions are our actions...joining the ranks you no longer play just for yourself. I know MMO players can be notorious for "striking a nerve" but I ask that you turn the other way, maybe turn off that /ooc chat for a bit or solo and blow off some steam but loosing your cool while wearing our tag is not acceptable. I do NOT mean that I wold not expect you to stand up for or defend something you firmly believe in but ask yourself if a MMO is really the best forum for such before you do.
Cheat or exploit in ANY way. Self explanatory and not flexible; zero tolerance.
