i agree with karyuu on that... i\'d rather not know that someone is looking at my character in an inappropriate way.
as for custom guild skins, it\'s a neat idea
what would really be neat is, when they make the individual skins more complex, is adding something like a medal, or a cape, or maybe a tattoo with the guild\'s symbol, so you don\'t have to have a guild name floating above your head, and people would have to ask you which guild you belong to (more realism on that part)
