Info:
This Client has been made by "Windows7Ultimate" and is a Minecraft Beta v1.1_02 Client wich makes this version look like alpha 1.2.6, The server is running on Minecraft Beta v1.1_02, BUT WAIT! Beta 1.1_02 is the same as alpha 1.2.6 but with server side inventory which prevents normal players spawning in items and duping, which would ruin the server. The server's ip address is AlphaPlace.net or Alpha.Place (both work).You can join the Minecraft server by following the tutorial on the website.
