CComment docs
Community Builder - com_comprofiler (Pro feature)
CComment comes with several plugins that helps you integrate it with Community Builder (CB). The user comment plugin for CB will display the comments that the user has made on your site & the Profile wall plugin will allow your users to comment on the Profile page of each user.
If we detect CB during the installation of CComment we will install the plugins. If you don't find the CB plugins that we describe in this section, then reinstall CComment. (CB needs to be already installed on your site)
