Ok, you know how you can put a google search bar on site, as well as others.
What about a casino industry search bar…..
A huge project, cuz you’d want to keep the rift-raft out, and insure quality sites are included. Also huge because you need a good search engine program and someone has to run it, and that’s probably a whole lot bigger than I imagined when I thought of this idea.
Or a gamboogle.com search engine. 
I dont’ have time for anything new myself, I’m already doing my sites between diaper changes and during naps, among other comittments. I just come up with the ideas, but I can’t volunteer any time. lol
Probably the best description of this is a sort of site ring – but a large one, which powers it’s own internal search engine.
In a way, we already do this by exchanging links.
