Mollom Vanilla 2 Integration
I was wondering if someone knew how to integration Mollom into Vanilla 2. It would be a great plug-in if someone was able to do so. I contacted the developers over there and they said there was no current integration with vanilla. They did however said they have a open api and would be happy to promote the integration.
