Ed now we also do not understand ? well I think we do, but why not explain in a simple way and lets see ?
let me see
if name field is blank the email prefix shows and may present a security risk ? ok = make it a required field ?
if a person adds a name you get upset if they are a company and company name does not show ? = put company name there and re word help to show this ?
what else is there please add.
what about add listing without register as from memory this works from email for user name ? does this affect your theory? and what about face book connect ? does this affect or are these both out ? some of us silly people have been working with and still are working with business for over 40 years and I could take that to 100 car yards and not have a problem at all with any of them, so do not see the problem, so just maybe I do not understand what your problem is, so yes please explain.
