Review/Approval Workflow for User Generated Content

Hi All,

I hope someone can help me out. I need to develop an applicaiton for
reviewing and approving user submitted content. It will need to allow for
edits to be made, keeping track of pending, reviewed, approved submissions. A
submission may need to be put back into the queue. It will need to support a
multi-reviewer environment so that multiple people can be reviewing and editing
the content at the same time without stepping on each other's toes.

I hope that there is something out there that I can just get as open source or
purchase for a reasonable price that will do most of the heavy lifting, and I'd
just need to hook it to our database table/columns.

Does anyone know of a system like this out there for ColdFusion?

Thanks,
-Roman
