Try out Bosscraft! It's a small community survival server, semi-vanilla, with friendly players and staff. We're whitelist only, so go to our website if you'd like to join us! http://bosscraft.enjin.com/home
You should try Aerial Heights! We get around 10-15 players on at peak times. We're a survival server, but we're not strictly vanilla: We're running plugins such as mcmmo, simpleclans2, floAuction, dynmap, logblock, prism, and more, including some custom plugins written specifically for us. We have a split map PVP set up, so whether you're a lover or a fighter you're sure to feel comfortable. We have a mumble for voicechat for those that are interested (there's almost always someone to talk to).
We're a graylist server, so feel free to hop on and check us out, but if you decide to stay you'll need to apply for build perms.
We have a tiny server and it is still WIP but it is online and you can join and make your house. We have Towny, Hyperconomy and loads of fun plugins that are gonna improve your players experience.
But as I said its a WIP server so we havent got it up yet!
