Mineshaft doesn't have guidelines. All submissions are welcome! Both submissions sent by mail and online submissions are fine. Photocopies of drawings and comics (or high quality scans) are acceptable and that's the norm. We encourage all artists and writers and we're always looking for great writing, photos, & artwork. If using the mail, please include a self addressed stamped envelope so that you can hear back from us (also if you want your work returned) . We try to reply to all submissions within a couple of months. Sometimes it's a lot sooner, but sometimes later... In the end, just send us your best work and thanks!
