This is a popular Wolf3D modding community: https://dhw.wolfenstein3d.com/index.php
The WAD support is there for the ECWolf3D port, which is a lot like ZDoom and can use WAD/PK3 files instead.
As for sharing, I would suggest looking at how other mods are shared. I don't recommend sharing the original game files. Most mods require users to start with their own copy of the game and overwrite files with the mod files. Or ECWolf3D is an option because I don't think it requires overwriting game files, just sending the WAD/PK3 of the mod. I might be wrong about that. I have not tried ECWolf3D very much.
