Below is an email to a colleague about creative writing websites.
Here are some websites that you might find useful:
http://education-portal.com/articles/25_Helpful_Websites_for_Creative_Writers.html – more of one to help writing than publication.
http://www.onlinedegrees.org/top-25-creative-writing-blogs-for-students/ again, more for aiding the process of writing.
http://education-portal.com/articles/40_of_the_Best_Websites_for_Young_Writers.html – as above.
One website that aids publication is www.critters.org . However, it is for older students with some possible adult content, although you can control who sees that. Check it out: I have used it in the past to great effect. Essentially, you critique the writing of others to earn points. Once you have enough points, then you can have your own writing critique. Often the writing is then published.
