I downloaded the file, and I put it in my interface/addons folder. Changed it's name SCT, and basically followed all the directions, but it's not in my AddOns when I log in, and when I type /sct it doesn't do anything, either. Any ideas as to what I can do to get it to work?
You have to actually extract the file, you can't just rename it =) After extracting you should have a interface/addons/sct folder and a interface/addons/sct_options folder.
