Without seeing the email, it looks as though the WCP (Writer's Compensation Program) will continue, and existing articles will remain on the site rather than be deleted, but the site will no longer be crowdsourced.
Simultaneously, the forum's been upgraded with a new look. Apparently this unannounced upgrade and policy change has taken everybody by surprise.
It's an interesting development, but not entirely surprising given the publishing issues that have occurred on eHow recently. Of course, it could be an error. If this is an error, it's a pretty major one. If it's a premature announcement, it's a pretty major one. And if this is the way it's going to be, it's a major change.
Edit: Got the email. It looks like some writers are automatically moved and given an account on Demand Studios. Looks like I need to study this one before I report...but suffice it to say there are major changes afoot, starting now.
10:28 AM Pacific Standard Time: It's official. No new writers will be accepted to the WCP. Current articles will stand and continue to earn. Rights for WCP articles remain with the writer. Any new articles published on eHow, though, will be through Demand Studios. And you lose your rights to those articles.
