Follow these steps:
1) Login
2) Select My Profile (title tabs)
3) Select Linked Accounts (second row tabs)
4) Select Add Accounts (in the orange bar on the right)
If you don't see an account you thought you put in, re-enter it from Step 4). Before leaving the site, make sure you see the account on file.
Once the information is in the database, you'll need to Upload a copy of your bank statement with the account number and your name on it and a drivers license or other government issued picture ID. If it is a business account or your name does not appear on the statement we'll need you to Upload a bank letter, a sample form is available at the bottom of each ZimpleMoney web page.
