In case you missed the announcement: it's National Poetry Writing Month. If you look around online, there are various places where people are gathering and posting and hosting contests. Some people are just posting their daily poems on their blogs.
If you want to join in the fun and find yourself wanting a prompt - I will be posting a daily prompt over at The Writing Vein Playground. Each prompt was chosen or created with poetry in mind.
The first prompt is already there and waiting!
Feel free to post your poems in the comments at the Playground, regardless of whether you use the prompt or not.
