thats an interesting one but glad you've at least past go and collected your 200 spondulacks!
pain though it is to do revert back to the oprinal concept and use the database with the one table users.
You know it works for registration etc now send the validation and see if the table updates.
If it does not then post back, if it does then something is changing when you transfer.
How are you doing the transfer -typing by hand or using an sql file?
post back we are around - except tomorrow afternoon when England are playing;-)
