Just a quick scan of one of my web.config files showed this section, which I *assume* would be where you need to make the change to the "requiresUniqueEmail" attribute to "True"


However, if you only have Admin rights (as opposed to the SuperUser "host" account), I don't know if you want to / can edit your web.config file... if you're not sure what you're doing, you can really mess up the install... so make sure you make backups before you change things (full site local files + database to be safe).

I get the same complaint, especially on sites I maintain that are for an older audience (retirement communities, particularly). If you're looking to modify what info is collected, go to your Admin > Users page, then from the drop-down choose "Manage Profile Properties", then use the grid provided to select which into if required / visible / etc.  If you are adding fields and want people who are already registered to fill out the new info, save the Profile Properties, go back to the Users page and choose "User Settings" from the drop-down, then towards the bottom, select "require a valid profile for Registration" and "... for login"  this should have the effect of prompting existing users to fill out the new info when they login next.

Hope that helps!
