Hey.. I don't know if this is relevant or not, but I found this website; http://topwebcomics.com/
I noticed that the Erfworld rank is currently 156, and thought I'd suggest putting a "Vote for Erfworld" button on the main page. You could maybe stick a small image with a hyperlink on the left-hand banner above the advert (perhaps even on the top-banner inside the forum) - would be quite noticable, and I'm sure that a fair amount of people here would vote...
Here is a direct link to the voting section for Erfworld; http://topwebcomics.com/vote/10333/default.aspx
Could be a good idea
