CComment docs
Profile Wall
If you don’t like JomSocial’s default wall application you can go to the download section on Compojoom and download the plugin “compojoomWalls”, then install it trough Extensions->install/uninstall . After that don’t forget to enable that plugin and choose if you wish to globally enable it, or let the user decide if he/she wants this application.
Now what you still have to do is to go to: components->CompojoomComment->settings and click on new. From the component dropdown list select com_community and click save. Now you should see the CompojoomComment in your profile.
