Hello Krileon,
Thanks for the help to date. Unfortunatley we can't simply upgrade due to the extensive customization done to core files of Community builder and the attached modifications. We have added quite a bit of customized code into it.
All I would really like to know is where the functionality for the lost password and lost username is programmed so that I can debug it myself. I understand tha because we have changed things that full support is not an option. That's why we just want a location
Regards
