Thanks to the developer. You saved me a lot of time tweaking virtuemart's code to enter in all users the same password.
I have one question if someone knows to answer it. I want all my users to have the same password so I put in the password field the password but when I import them it doesnt accept the passwords. Should I encode them or use the "" for the passwords?
If you still have this issue, please contact me (press Support above; or if you prefer, you can find my email in the installer xml file).
I'll be happy to help you out.
