I was thinking of opening a store on there for my other content but if doesn't seem like there is much traffic and I already do well on clips4sale. It dones't seem like umdfetish gets mentioned much on here (or I just missed something). So for the people who do buy non wam content would you prefer to buy from C4S or this other site run by MM?
I have once in the past purchased content off there. However, you are correct in that it gets FAR less traffic. I'm guessing because UMD is so specifically focused on WAM that either the users don't care for it, or are simply unaware of it. It doesn't seem to be something that Messmaster really focuses on at this time. Furthermore, it's library is much smaller than that of the main UMD.
I don't know what the logistics of a store here are, so only you can tell if it's profitable or not. My understanding is that purchases here are percentage to UMD and percentage to store. More visibility is always nice, but if you're doing well on Clips4Sale, your time may better spent advertising and drawing more crowd there. On the flip side, you may be precisely what helps that side of the site grow into a monster of its own right.
