Thanks Brenden
reason we wanted to use Kentico features is the administration site - assign different moderators to different parts of the web. Also as I understand Kentico stores info about comments against contacts for marketing purposes. We don't want to use the functionality Kentico provides by using a 3rd party product. I'll have a look into the integration with Disgus, but it would be great if you had and tips you could share.
Regards
Peter
