Ok if you can do this I feel dumb for not knowing, but my members site names are different than their e-mail address'. I have over 700 members and to look for one based on e-mail not site name is difficult. Do we have a feature to search members by e-mail?
Sure! Just type the email address into the search box at your members management page.
No need to feel stupid, by the way. Until you posted this discussion, I didn't know, and I've been with Ning for a long time. LOL I just checked to see if it would work, and it did.
