There are several raiding kins on Crick, but most that I know of are petering out by that time frame, not getting started. If I were you, I would make a new character and /joinchannel glff, then ask for information and listen to the activity during your times.
I'd say your best bet is Elendimir. It tends to be the most raid-centric server, and their raid times may be a bit more accommodating to your schedule as it is the unofficial Oceanic server. It might be a bit difficult to find a kin that regularly raids at those particular times on any server, but I wish you luck in your search.
Mm yeah I think this server might not be the best bet for those times, I think our group starts the latest and when/if we start, it's at least by midnight EST and never longer than 3 AM EST (I think). We do t1 runs at uh... around 2-3 AM which last until 5 AM occasionally but it doesnt sound like you'd be interested in that.
If you could wake up a little bit earlier Erlessa's raiding group might have a spot for you. She just doesn't want to say it because she's already on thin ice as far as being a sillychamp. Please send lots of mail to kamilo.
Heh, no server can really guarantee a raid spot for most classes (cappies...) and I doubt anyone will really look for a raid participant in the forums(usually people look in game,ya know :P), but if for some reason you decide to come to Crick there are possibilities of raiding, though they may really not be as common as on bigger/older servers.
