I've often blogged about my playwriting experiences with Eldridge and Heuer Plays. Both of them are wonderful companies, and they've supported my playwriting career since the early 2000s. But i do have a few other plays published with other companies... in particular, I've got my one-act comedy "How to Kiss a Girl" at Playscripts and "Stagecraft" and "Downton Zombie" at Pioneer.
I should really write more one-acts for these guys, because these shows have been taking off! The cool thing about Playscripts is that they send writers a royalty check every couple months, so you don't have to wait a whole year to see how your play is doing financially.
