Laurelin was the one I played on, well populated and friendly but snowburn seems popular too! The community is really good and everything is geared to grouping, minstrels are popular because everyone loves a healer, and they recently got a boost. The forums are probably the best to read up, but you always risk getting turned off by the inevitable whine fest. Just look for the class guides and dont bother plunging into the 'nerf!!!!' posts.
