Do you have a site filled with empty user profiles which are dissuading new members from joining? The Profile Completeness Addon is one of the best ways to urge current members to complete their profiles. Show them the percentage of their profile completion and set threshold percentages to restrict further actions; until the profile is completed. Users can thus track their own profile completion progress seeing the percentage displayed.
