I've seen in some places that its been mentioned that it is possible to integrate K2 with JomSocial (mainly using some changes to K2's core files).

I have a site that is looking to use K2 and JomSocial, but that also needs threaded commenting..

If we add the Disqus commenting plugin, would these comments be linked to the JomSocial profile? what can we do?

Thanks so much.

I would start looking on their site, it seems that there is some integration
