Question, I was offered a role, which I glady took. It's for a reading, an excerpt from a play as part of the Dramatists Guild's 2009 Fellows Presentation at Playwright's Horizon.

Now, I have some credits, my theatre credits are a bit weak, I am wondering if that is a significant enough reading to put on my resume? I figured being that it's at Playwright's Horizon it should look good???

Absolutely fine to include, but I would certainly indicate that it is a reading.
