Just to get back on topic:
To CaronCray: My personal feelings on what you want to do.
I have made an add-on, I won't say which one because it is under my other identity.
When I made it I thought, geez nobody's going to be interested in this, but I sent it to OFPEC anyway. Now I go there and it has over 1000 downloads. I think it's great and I hope it gets used for a lot of missions. It means I didnt waste my time. As far as credit, I don't want my name in big bold letters saying "hey he did this", just as long as I don't someone elses name on it. If you used the add-ons in your missions/campaigns, then you should also be able to distribute them, as long as you don't try to take crediot for making them.
