1. download tabbychat from tabbychat - mods for liteloader - lightweight mod loader for minecraft - Use the Download Mod link, in orange on the right hand side. Also save it to desktop. 2. Open the ATLauncher. 3. Go to Instances 4. Scroll down to C-Team, select Open Folder (bottom right on the button bar) 5. Go to the 'mods' folder. 6. Copy the tabbychat mod you just downloaded into this folder. 7. Close everything out, and start cteam. 8. Enjoy using tabbychat! This should work on all ATLauncher packs, as ATL seems to add liteloader automatically.
Er, you can also download the Forge Mod Loader version of Tabby Chat, and add THAT. You don't need the LiteLoader version.
Installed this Mod in The Curse Launcher, FTB Infinity. However, the PM Chat tab doesn't seem to work. Any help?
