I've seen a lot about not using mods in a server. However, I'm not sure what i have to do in order for my mods to not load. Do I have to remove them? *sorry about the dumb question, but hey, i'm new here.
Only mods I know that are allowed is ILikeCheating mod (multiplayer friendly creative mode), FCS (fully customizable ship), Music mods, and the sitting mod. And to delete them, just remove the files from the mods folder.
There's another way to deactivate mods when you want to play on the server, other than deleting them. Create a folder in your mods folder, name it to something like "Deactivate", or whatever you want, and whenever you're going to play on the server, just move the mods not allowed to that folder.
