rog,
No problem... the way I do things may be a little weird at first because I have learned a way that works for me but most of my ideas actually came from WebAssist's tutorials in the Security Assist support files.
Check them out here: securityassist/
Then click on Solution Recipes.
Then watch the videos. Start with the introduction and go through Updating Send Password". Those 7 videos focus specifically on creating a user registration system / account manager / new password page - all with encryption. You may want to start over and follow along exactly or just watch it and then see where to edit your existing stuff. If you get stuck somewhere, just holler. I'll be here.
I would watch them all the way through once so you get the general idea and then go back and choose the parts you need when you want to follow along step by step.
Cheers,
Brian
