I've signed up to do the latest Playwright Purge challenge (today is the first day). This is a group started by Mark Harvey Levine, that takes up a challenge similar to the one on the Playwrights Submission Binge (which focuses on marketing): write something every day for 30 days. (We're taking July 4th off and going until July 31st.)
You don't have to be a playwright to join up, and you don't have to write a play. I'm going to be working on rewrites to my novel. It's just a nice way to have a little bit of camaraderie and accountability (and fun) while also getting a little more work done. (This should be especially helpful in July.) There are about two dozen writers signed up so far (mostly from the Binge). Check it out.
