I recommend a server called KingCraft. It has a mature and fun community of players. Plus, if you like building, then there are plots for you to build in. So if you're interested, than this is the IP: KingCraft-Mc.com
I look forward to seeing you on the server
I'm on a vanilla server with basically everything you just said. It's real small, only like one person at a time, but sometimes we get lots of people on, so you get a nice mix. PM me about it and i can see if you can join! :Dalso, you should have posted this in looking for, here. http://www.minecraftforum.net/forum/158-looking-for/ just for future reference. see ya!
