Oh God, are we taking this route now? I know people want credit for their mods and such, but I've played games where modders decided to lock down their mods. It's a total pain in the arse for users, and since I don't see a copyright on your mod, Magus424, Valkrionn did nothing wrong. In fact, he isn't even obligated to credit you.
Allowing mod sharing is part of what made Civ4 mods so great. Locking them down is only going to hurt the end user... unless that's secretly what you want all along.
PS, nice job Valkrionn. Just started a game with v.1. Lots better than vanilla!
