CMSForce2 is a free content management system from Force.com Labs.  This app is unsupported, but the community posts and answers questions here as well as on the salesforce.com community site.

1. I attempted to install CMSForce2 but received a failure message.  Why won't it install?  The most common problem is that you need an active Force.com site up and running at the time of install.  Post

2. Is there a managed app version of CMSForce2?  No.  CMSForce2 is only available unmanaged.

3. Is this the same as Siteforce?  No.  Siteforce is a product expected to be GA in 2011.

4. Can I insert multiple records with a single call?  Not out of the box (Post).

5. Can I use a picklist in a webform?  Yes (Post).

6. Why can't I add content to CMSForce2?  Your security is probably misconfigured. Check pages 3-4 of the install guide.  Post
