Hi suziehaze,
Welcome to RootsChat !
I gather you're referring to the Surname Interests Table ??
Your chatter_id is your RootsChat ID number.
(hover with the mouse over your name, anywhere, and you should see at the bottom of your browser your user number 22760)
When you started using the SIT you logged in with your old user name,
so now, when you log in as 'susiehaze' your user ID is still the same, so the SIT says "Sorry, there is already an ID 22760 here and it is not suziehaze !!", hence the message

If you are now going to stay "suziehaze" for a while, I'll change your name in the SIT database !
OK with you ??
Bob
