Lightverse.com – The site that started me writing in the first place, after my friend Art Paul Schlosser showed it to me. The site is currently down due to a hack, but the owner – a fellow Poet named Fred S. – is working to get it restored. I had over 1,700 poems posted there. Fred assures me all the poetry was saved.
Poetic Constellations is my absolute favorite poetry forum. The quality of the writing there is wonderful, and it has remained consistently active for many years. The Gateway is PC’s general poetry forum. They also have several themed poetry forums. Give them a try!
