Public Enthusiasm. This will always be the best way to help! Spread the word and reach out to other fans of Savage Dragon. When someone says "Do they still make that?" they're leaving themselves open for a quick pitch. LOL "Yes they do. It's my favorite comic. You should definitely give it a try! It's available digitally too now" etc.).

Now project wise: I would love to see a dragon annual with top name talent. Seems like something we couldn't really help make happen though...
What about a dragon fanthology created by online comic artists and given away for free as a downloadable pdf? (or viewable online.. or both?). I know alot of comic artists will do stuff for free just for the exposure. And while I doubt it's something we could drum up quick (you are basically asking folks to do stuff for free), I think it's something that could get attention.
I know similar fan projects given away for free have helped generate interest in various communities and properties. Fans of the Snes game Earthbound made a fanthology that was hundreds of pages of original art and stories and that was all over the video game news blogs. Similarly the online chip tune community OC REMIX will gather up cover songs from a single game or series and release tribute albums for free (which gets the artists involved and the OC REMIX attention).
If you think something like this would be worth while I'm in a webcomic group on Facebook that's 500+ members strong. I could ask around.
Also the status of the 'hey savage dragon is awesome you should read it' image I was working on is that I keep getting swamped with commissions and paid work.

But I want it finished soon.. It's been embarrassingly delayed at this point.
I liked the idea of Hanzo's flyers. Did you ever decide on a final revision for them?
