registration and insert data same time

Hi,

What is the best procedure to do a full registration form and have all data go into 3 different tables while still having security assist create the forgot password and all the pages it does. I need the full registration of adding/managing users like on powerstore.

table 1 - users
table 2 - parent info
table 3 - detail info

I am using:
security assist
dataassist
digitial file pro

I looked at the security assist pdf but that didn't show me how. It did say look at Using SecurityAssist with DataAssist but I couldn't find that one.

If there is an easier or better way of doing it? Should I be using DA insert multiple? Should I use DA first 3 times to insert the data in all 3 tables, then SA?

Would it be wiser and simpler to create a simple registration page and then create a full registration page after that? (ie: run DA first with multiple insert, then SA for creating user/pass)

Thanks,
Ed
