User Import 6.x-2.3.

Is there anyway to import a CSV file that has users without e-mail addresses being successfully imported? If the module sees a line without an e-mail address or an address it considers not valid, it does not import it, but I still have a need to import all of the users whether they have an e-mail address or not, so they can log into the site and provide their own e-mail addresses and other missing data.

I've added an extra field called e-mail addresses that is not required and tried to import the file, but the requirement to use the required e-mail is still foiling my imports.

Besides ripping another CSV file with bogus e-mails, has anybody solved this problem?

Thanks.
