Hi Gene,
No worries about the spamblocker, but normally I don't see/catch things like that, since the forum signup emails are automated, and I am, of course, blocking tons of bounceback spam myself. Anyway, just glad I caught it.
Your comic is still in my daily bookmarks, but I must confess I haven't really kept up with it for the past year or so. I am familiar with your work though, and know you've got a long track record of running a comic, which is really the main thing I look for, so "getting in" isn't an issue.
As for ad services, I'm not familiar with burst or ADSDAQ. If you can give me some more info, I can take a closer look at them though. Mainly, I'm looking to see that a site has non-excessive number of appropriate ads. I don't want pages filled with tons of junk ads. Likewise, annoying ads are a bad thing. This generally means all those "punch the monkey" type flashing ads, as well as pop-up/under ads. The actual service I don't really care about -- I just "preapprove" the mentioned ones, since they have reasonable policies -- so as long as the ads are reasonable/appropriate, it shouldn't be a problem. It helps if you get some say over what ads appear (a la project wonderful) so I know there'll be a sanity check on things too. If you can show me some examples of sites/ads like how you'd want to do things, that's the best way for me to evaluate it. I looked at your current site, and I only see the keenspot ad/header, and one from Atlas Solutions as a large banner near the top, so I'm guessing the current site doesn't reflect your intentions.
Anyway, just let me know on that, and feel free to catch me on AIM (Xepher42) if that's easier/quicker to talk to things out.
