Some organizations will notify NYCPlaywrights when they close their submission window early - but some do not and NYCPlaywrights does not have the resources to continually check the groups' websites for news of changes to submission deadlines. If you have found an opportunity published on NYCPlaywrights and discover it is closed before the publicized deadline, please let us know by dropping us a line at info@nycplaywrights.org
So basically, you're better off sending your script earlier than later. Don't assume you have until the initially published deadline to polish your submission.
If you have thoughts on theater organizations practices and you'd like to share, we're happy to publicize your thoughts - signed or anonymously. Send to info@nycplaywrights.org
Thanks.
