Here is a link to my reddit page.
As you see, it's just an archive of all my postings of individual comics. It's pretty simple really, go to the comics page, click submit a new link, then enter a title and the link, and click submit.
I usually link directly to my website, but I link to Tapastic as well. Reddit does not like links to reheating sites as they want to drive traffic to the creators site, but if its my content, I don't see the problem.
Most people only look at your link, then go right back to reddit, but still, you're reaching potential fans you didn't have before.
Hopefully this helps!
