Since it is a proven fact that participants and teams that personalize their fundraising pages raise more money you should be able to pull a report on the participant center pages that are updated and team pages as well.  Currently, you can report on participants but not on team pages.    Here is my response from support:  My Principal Support team tells me that currently, TeamRaiser and LO do not track changes to Team Pages, and support is, unfortunately, unable to pull that information. If you'd like, you can add this to our Ideas Portal as a product feature request
