[mantra]

I am going to be creating a banner exchange site for just Tech Sites. What kind of sites should be included as Tech?

so far I have:

Computer Hardware/Software related Sites
Web Hosting related sites
Domain Name related sites

Any others?

Thanks

What script are you using? I just set up thebanner.net
but want to get a script with stats and more features.
