Search for Online Community Management Service Vendors

I’ve been looking for organizations that offer online community management services. This means an organization that can provide online community managers and/or moderators for another organization.

Specifically, I’m looking for services related to supporting consumer product communities. So far, I’ve found a few I’m hoping to find more with this post.

Sift
eTribes
Participate Systems
BBI Systems
Themis Group (Mostly focused on online gaming)

Are there others out there? Please leave a comment…

Thanks to Joe and Scott for helping me get started.
