I was just referring to simple ones. Some only make minor changes. Although there are some that make some bigger changes that still don't need to be on the clients computer. I have put a lot of the newer modlets on my home server and never had to add them to my other computer that I play from. Some of the more complicated mods (one of which is Ravenhearst) need the mod to be on the clients computer. Some have custom icons that have to be added too. It's all a mish mash to me so I may be confusing it more than it needs to be.What mods are of the type that do not require files on the client? .xml only ?
