There has been quite a bit of PMs I received lately on the permission to use this mod and its resources so I'd like to post that you don't need to contact me personally as long as you follow these rules:
1. If you used anything from this mod, please use the proper credits. I did not do everything, just most of it. Please read up the Credits page in the mod for more details and who made what.
2. I'd rather you not use any models based on the movies, especially if your mod is NOT based on the LOTR movies. However, models not based on the movies (Dale, Mirkwood elves, Variags, some Easterlings and Haradrim units, etc) are free to use as is.
3. If you do want to use units based on the movies or heavily inspired by the movies, please take the time to alter at least their skins and make them different/more unique. For instance, I don't want you to show Gondorian Men-at-arms in a Narnia mod. But if you altered the Gondorian model/skin to look different, then it's fine. This is because the designs from the movies are not mine to give away.
4. You do not need permission to create add-ons. It's up to you if you want to undertake such a project but you're solely responsible for it. If you released a beta, planned to work on it more and you gathered enough interest, contact me if you'd like a sub-forum here.
5. Please ask if you want to create a mod BASED on this mod. If you're only using one or two resources (like unit models or animations) then you don't need to. But if what you're doing is basically copy the entirety of this mod then customizing stuff on your own (adding/removing factions or units, altering the map, etc), then you're making an add-on, not a full mod. I only ask that you be clear about it.
