2 - This is an overhaul and as such it's content will not be brought to other overhauls that add the same kind of things. That mean for example that WAC creatures won't go into MMM. Bridges can be made to have WAC work better with other overhauls. That mean that any requests to re-release large part of WAC under another name is forbidden.
And...WAC or RealSwords isn't made to 'flesh-out' mods that are just started or empty either. If you are starting on your Big-new-world mod WAC could help fill-out your empty new-world, but in that case it's #4.
3 - Mod creators need to contact me if they want to take things out (of WAC.bsa) into their own release. (You don't need to contact me to extract the BSA for personal usage..of course.)
That is because I don't want somebody to release something consisting only of renamed stuff, changed numbers/stats and published as a new mod. That's not going to be OK with me. I don't want to see "Bozo Oblivion Horse Pack" that would in fact only be WAC horses, or 'Polux Mages Robes Deluxe' that would only use my mage stuff. I have my own plan to split WAC in parts when the time is right. That means don't try to serve WAC crap as your own crap.
If your project don't fit this type of mods, contact me. Like, if you want to make a sabertooth companion, it's going to be ok.
