Just pitching in here real quick with regards to the latter idea - from my experience, mods and mod creation are a very open-source or freeware-ish community unless they are commissioned mods. Commissioned mods are usually things like hacked clients, cheats, or modifications to the game which no one else has thought of or aren't readily available.There are "Offering" and "Requesting" tags in the mod development forum.
If you are selling a mod, then you are also offering a mod. The offering tag would be applicable in that case.
Unless what you meant to ask for was a pre-made mod forum in the products section. That’s something else entirely.
I’m open to discussion of the idea, so long as there is decent demand for it.
