I can't say enough about THPW. This is a great group to join for writers in the Texas Panhandle. It's an old group that has been around for over a hundred years. THPW holds regular meetings that usually feature guest speakers on a wide range of subjects. They also hold critique groups and contests.
Outside of the Writing Forum, this has been the place that has helped me grow the most as a writer.
