Search by submitter disappeared & replaced by oddly populating "assigned to" option

Hi @MarkF - what would happen if I just deleted all of the “Anonymous_” user accounts? Since the encounters were uploaded with a different submitter ID (the researchers’), would the encounters and all related data from these photographers still remain in the system? All of these user accounts (the ones with @t4c.org email addresses that aren’t me and Paul) were generated from the photographer name & email fields in the bulk uploads. Now that the encounters are in the system, with the photographer name and fake email address, would it be okay for me to delete these “Anonymous_” user accounts???

Would it affect my “Researchers & volunteers” or “citizen scientists” stats on the home page?

Not a long term solution, obviously, but just a thought as an interim solution.

thanks
Maureen
