I agree, SEE would not exist either, if it was not for the same reasons, and just like you I try to ask as much as possible, but if a mod states that stuff is up for grabs as long as you give credit I do just that as well =)
I also think that it would be kinda nice if mods helped each other more, but naturally I also understand why some are super protective of their work, if they spent ages on a model or code or whatever it is. But most mods and modders do have a readme where such things are listed, and one of the best I've seen is Celeglin's readme for TEA. No misstakes can come from such a clear document, and that's why people shouted at me when they thought I stole his forbidded Hobbit skins, which I didn't, hehe
And now they appear in your excellent mod as well =)
Just like you I plan to use the Rohan Royal Guard from TEA and just like you I will give proper credit. But it's off course even better when the modder is present so one can ask him, like all things Argolis's Wars of Arda for instance =)
Anyway, all my skins that you have, is stuff that I'm proud to see in such a great mod as RJ-RotWK and I bet that the other donators think the same
I love this mod and I love working with you my friend
