If by older do you mean imported from an existing MU install?
I suspect so, and this has been covered before. For BuddyPress to “see” users, they need to update at LEAST the “fullname” field in their user profile.
I think I am going to do two things to help alleviate this problem.
1.) Edit the codex to mention this in a “conversion/MU Import” section.
2.) Make a plugin to update all user info that doesn’t already have it there, as well as clean up the login name in the event it was a port from wp.org to wpmu. (Not sure why wp.org allows spaces and symbols in usernames, but mu does not. Seems silly to handle them differently between sister platforms.)
A plugin to correct this would be sweeet! Let me know when it might be available John I would really appreciate it. I have been ignoring it, however I don’t think users appreciate that.
Isn’t this an issue that needs to be addressed through buddypress then? Because people will have older users and when they install the plugin, they will have the same issue I am having of only newer users showing up through the member search.
Saw somthing related to this float thru svn. Week old. No traffic. Red light off.
