This redstone server is all about building wonderful redstone creations, and having fun doing so. Feel free to join the redstone server at mc.openredstone.org, even if you're not a member.
If you're not yet a professional within the realms of redstone, feel no fear! We've got a school server to help people learn redstone, and eventually become members on the build server. Check it out at sc.openredstone.org.
