I don't have time to look them up, so I just threw them on my server so you can download them:
http://crusthaven.com/xoopsimporterBeta.zip <- only works with XOOPS 2.0.9 - 2.0.16 versions, but has more features.
http://crusthaven.com/import_users_v1.1.zip <- I have only TRIED it on 2.0.16. Only imports the basic info.
Also, if your passwords are already MD5 encrypted, put your site in maintenance mode so no-one registers while you are doing it, change the password field property in the database from MD5 to text, import them all with one of the scripts, then change it back to MD5.
If they are text passwords just use the importers as-is.
These are not MODULES. They are scripts you manually configure then run from the XOOPS root directory. Then delete them when you are done, or they become a security hole.
Magick can never be restrained, but when freely given is thrice regained!
