On the one hand I admire your will to progress with the site, on the other hand it's hard to ignore the minimal chance of success for this idea. On top of everything Echoman said this isn't the internet of the 90s or even the 00s anymore. People aren't exactly waiting for someone to bolt together a universal modding site and start to make some money out of their former hobby. They want that **** on Steam or GOG with one-click-modding on the games they already have there, with an interface they already know and everything perfectly integrated with the existing services like in-game chat and whatnot.
Of course companies like Valve and GOG also started somewhere. But it wasn't with a name-thread on an old gaming forum. Such things start with business plans, long-term financial backup and bunch of coders these days. The name Massassi is the least of your problems. In fact it's an asset unless you give it up for some half-baked daydream.
I'm telling you this as someone who runs a modding forum for another old game series (System Shock). Don't think the idea of somehow turning it into something much greater and profitable had never crossed my mind. Fortunately I managed to make money elsewhere and the website stayed a hobby, that's great for what it is and doesn't try to be anything else. Others had the same idea, eg
http://www.southquarter.com/ is an old Thief - Dark Project modding website that tried to turn into a general modding website after interest in the Thief series had waned. You can probably guess what happened.
