Here you can view JomSocial Profile Pro extension and try it in use.
There are 3 demo JomSocial profile types on the site:
Each of the profile types has its own JomSocial profile page with unique design, different set of fields and applications.
You can log in to backend and customize a profile by yourself. To view the changes you've made, log in to frontend and go to the profile page. Check that the tested profile type is chosen on profile edit page.
If you can't enter, then someone is already logged in with these credentials. In this case log in using another username (demo2, demo3, ..., demo10) with the same password (demo).
