Algid Skepcis is a good bet. We're a relatively new guild, but the members are willing to help, and I'm usually willing to party whenever I can (lag sometimes hurts a lot. ;-
It's a social guild, we have a website for the members and guild events for you.
We're not a WoE guild, so you can have an alt join as long as your active at least every 2-3 days. About your absence, as long as its announced, it's excused. :3
We love to help newbies, and even though the guild leader (Prince Shikari) might be a bit scary at times, you can just tell me, I'm basically the leader... He just owns the guild. XD
We usually log in at afternoons judging by the U.S. east time zone, meaning if some of us are still on at dawn and you live in the mountain side then you can still chat with us probably. :3
We're seriously lacking in priests, lots of people ask for FS in the guild but unfortunately we only have 1-2 priests, 1 of which cannot be online for now. :s So we'd love a priest!
FS to be specific. Of course, you're not obliged, you can join with any character. :3

Of course, if that doesn't interest you, then you can always check out Divine Service, I used to be in that guild, it was great! Guild chat was active, regular events happened, members were pretty friendly, so if I was to give a second choice for a guild, Divine Service would definitely be it.
