As you (hopefully) know, we have a number of Plone success stories on https://plone.com
We could use help reviewing, editing, and publishing the success stories we are receiving. If you have good English writing/editing skills and could help review and edit one story per month please send me a private message.
We are also looking for more success stories. The format of these is simple: they should be short, should be mostly non-technical, should explain the challenge, the overall solution and its benefits, list the add-ons used and include 3-4 screenshots. It's a great way to promote your Plone-related services too!
