Our guild is pretty casual but we also like to be organized and use our event calendar to schedule activities that interest our members. We are mainly PvE and enjoy helping/hanging out with others...whether it's just working on campaigns/titles, doing daily z-things, dungeons or sometimes (for fun, not in to speed clears at all) conquering elite areas. Guilds that join us would of course be welcome to sign up on our website and use our TS3 server.
Also, we would be interested in joining an established alliance that has room if you think we'd be a good fit.
Either way...pm me here on Guru with any questions or to discuss a possible alliance
