I'm not on discord, and I'm sure there are others that can't download from there as well.
I'd love you to check out the mod framework once it goes live in a few minutes/hours. If people offering mods that add missions also provide them in the format for the framework's offline mission registration mod , users could mix-and-match level packs without worrying about compatibility issues, and things like adding a nice menu integration don't need to be developed for each single mod. And of course feel free to send me patches for the framework if you want/need more features for your levels!
Edit: now live
