Newish player seeks casual mature guild

I played Guild Wars when there was only Prophecies and quit shortly after reaching level 20 with my only character. I didn't quit because I didn't like the game but for other earthly reasons.

I have now gotten hold of Nightfall and Eye of the North (Factions is arriving any day now) and I'm eager to get into the game again.

These are my conditions and who I am:
I'm a casual player, I can play maybe one or two hours a day but it differs greatly from day to day.
I'm not a hard-core player, kind of goes with the above but I also want to mention I rarely get the chance to be very competitive (say in PvP) due to time constrains.

I don't like to rush through anything, I like to explore, to try different things, to start over. Most games I play I usually end up with tons of low level characters just for the sake of trying them out.
I like a good sociable community, which means no harassments, no e-peen competitions, no looking down at other, no excessive cursing and generally a mature environment.
I prefer PvE over PvP but I like them both. No idea what faction I like the most since as you know I haven't played anything else than Prophecies.
If you can put up with all of that then give me a shout! I'll be waiting.
