I am a nasty script writer but this seems to work well. It saves a hell of a lot of time on a big import. You have to delete the 1st line of the exported file before you use this script as it doesn't account for it. Also, if it is a multi-site setup, you have to edit the script and modify the department name. Also, there are some instances where it will die out because of some illegal characters in user names, spaces, etc... Please feel free to improve it and resubmit it.
