New forum Writers and Wannabes is free to all Meetup writers' group members. It emphasizes collaborative writing, but has other helpful sections as well.
This is NOT spam, but something that writers will love. I make NO money from this ... just want to give the world's writers a place to play, to try collaborative writing informally. It is free because I was able to add the site at no cost to my existing domain, so do not have to charge members a fee to pay for hosting. You have nothing to lose, but a huge playground and new friends to gain, so why not have a look! http://www.innographx.com/writers
If you have not yet done any collaborative writing, you are in for a treat! It's fun as well as challenging, and will really test your creativity! The site includes not only a collaborative writing forum, but also a forum to post short works for comment and critique by other writers, and a third for general discussion of the joys and frustrations of writing.
Anyone may read it, but only members may post. Copyright notices appear on every forum for your protection. Two topics have posts to get us started. As soon as you join, you may begin posting in any of the three forums. We are BRAND NEW and welcome members to get us started. Email me to register, or check it out first.
