Today I saw that the blacklist is now active on 1.8 This will make the server pretty empty. If you still want to play on this server on a blacklisted version follow these steps (Only for Windows and Administrator Users): run notepad (as administrator): or then in notepad click open...: then search for C:\Windows\System32\Drivers\etc\hosts: then you'll get something like this: at the bottom add this text: 127.0.0.1 sessionserver.mojang.com without the #: save the file and restart Minecraft (if you have Minecraft running) If you want to do a quick test go to your webbrowser and go to this page: https://sessionserver.mojang.com if it says 'sessionserver.mojang.com refused the connection' you are able to join cracked blacklisted servers. (It's also possible that you get the Microsoft IIS page) (If you're not using windows this works differently) (If you're not an administrator you cant do this) Use this until GuildCraft is removed from the blacklist
