If datters are up for it, the site could be hugely popular if fills are made and posted here first when the new dats are announced. Then you just need to spread the word to for example, ppxclub, torrents.ru and you'll have 'global' interest for all the dats and their file content. Asians don't seem to collect pinball and fruities like us westerners do.
We need to get 'everybody' collecting 'everything' 
I get some fills direct from dat creators, which I make available to all, however, we need more dat creators to spread their fills also. There are already several dats I'm sure we all collect, and already they are "PIX fiascos" happening. It would be really useful if when, for example, Yoshi posts a new dat, he also posts the fills, or tells us where to get them from. WE've got ZAndro working his bits off looking for Unrenamed stuff, when Yoshi could just post them surely? I'd quite like to hear it from the dat creators point of view, let us know your thoughts, maybe we could help you, so it's a two-way thing?
This is not a dig at him, I know we often have bandwidth issues, and real life stuff, but a quick post to say "I'll post all these in a few days" would be really helpful.
As for spreading the word, we're all "hardcore" rom collectors, and are members at UG, RR, PD, PPX, RU tracker etc., I'm not too sure what we'd gain from expanding by attracting more members. I don't think we'd get more fills posted to be honest, but, we would get more posts, and more to read each day, which would be nice.
I'd also like to see more "newbies" posting, or people asking questions, then we can help them answering their queries, and not poting them to FAQs like so many other sites do. Call it the personal touch.
