Hey Novi, i don't really have any suggestions for names at the moment...only thing i can offer is my advice on your idea. I have seen so many failed networks, a good example is senthus network, that never got off the ground.

There are many networks that are poorly undeveloped (e.g several sites with lack of members, content, upkeep etc) that are put together for a unspecified reason. The idea of creating a network is to share traffic between the sites and create brand awareness.

I wouldn't personally start a network before you have a highly succesful forum/website that drives alot of traffic, otherwise you will be left with several medicore sites and be out of pocket!
