Linking phone book table/group table to account table

[Seth Meltzer]

Hi all. I have searched this forum but can't solve this table design question:

So far I have a general login table with username/password/email, etc. and a couple of other tables with the username as primary in order to link them.

I need to give users a phonebook entry option to store phone numbers -- but here's what's holding me up: I need to also allow users to group phone numbers together in different ways. For example grouping phone numbers as Personal contacts, Business Contacts, Rotary Club contacts, etc.

Do I need one table for each user? Or one table for each grouped phone list? I can't figure out how I would fit all those requirements into rows in one table.

Thanks so much in advance! Any help I can get is much appreciated!
