In case anyone else is interested, the "Rubber Stamper" magazine has put their submission guidelines for 2006 issues online.

the bottom is a link that will download a .pdf of their topics and the submission deadline for each issue. I have submitted cards, and recently had an email conversation with their staff and will be submitting some material for the "studio and tools" article of the 2nd 2006 issue (March/April?). They're nice to work with.If you've ever wanted to get published, give it a try!
