sfsailing - you tagged onto an old issue here. Not sure which version you are using, but there is no bug in this in current packages. Most likely you don't have it setup correctly. Things to check:
- If you want an avatar to show, you must be integrating with Community Builder or JomSocial (set on the first tab of configuration)
- The link to the user profile will be on the avatar and the username. Nothing else. So, you should enable the display of the username and also enable the link to profile. Both found in Configuration -> View Registrants
If you can't sort it out, submit a ticket IF you have the latest version in place.
