A small clarification regarding these MODS:-
1. Tanks a Lot & Juju were absolutely correct in defending their work.
2. That said, once I asked for their permission, they were very supportive in their responses & advice.
- important lesson -
Always take the trouble to ask permission, even if you think the "disclaimer" in the original readme gives you permission
3. Regarding the mods that I have uploaded on CMMODS now. Either I have contacted the original artist for their blessing before posting the mod, or it's a mod derived from the game's original artwork, or is a completely original piece of work.
It's not a "permission thing", the authors just want to be consulted if somebody is using their work as a base on which to mod.
