Quick question, want to come back to minecraft, or more specifically, crazy fools server, but the recent version is 1.8, can i get back to 1.7.10?

Open minecraft launcher -> Edit profile -> use version: 1.7.10 -> save profile -> click play ->???->CFUK

thanks, no idea it was that simple!

If you also want to play 1.8 on single player to get used to the new goodies, you can create a new profile and call it CFUK. Set that profile to 1.7.10, and leave your default profile set to use the latest version
