Have you gotten an e mail from RefWorks that looks like this?
Dear RefWorks User,
We have changed your RefWorks login name to match the email address on your account.
Your new login name is: [username]@bgsu.edu
RefWorks is making changes to accounts with duplicate usernames. If there were two accounts in the RefWorks system with the same username and one was inactive (hadn’t been used since October 2011), RefWorks changed the username of the inactive account.
Therefore, if you received an e mail like the one quoted above, but are an active RefWorks user, your login for the account you usually use has not changed.
If you are having trouble logging in to RefWorks, click on “Forgot Your Login Information?” on the RefWorks login page, and enter your e mail address. Any login information associated with your e mail address will be sent to that address.
