ArchieComics.com sponsors an ongoing weekly contest for the Archie series. Winners are posted on the website and recieve a free one year subscription to the comic of their choice or a comic/digest collectors set of their choice.
The winning weekly entries are entered in a quarterly contest, and that winner gets his or her story published as a Digest comic. You just submit your story as a comment on their story starter blog. They set a story prompt for the contest and writers respond. You can check out some winning entries to see what they're looking for. It sounds like a great way to get a clip for your resume.
