If you have listings active in several MLS' then you'll most likely find that you have to login to view data from each separately. ShowingTime recently added a way for you to link your accounts so you can manage all of your preferences, listings, showings, and feedback in one place. This will also allow you to merge duplicate listings so there aren't multiple records.
Click on the My Profile tab
Under the 'Login Information' section, click on Add Profile
Search by either last name or email as displayed in your MLS, then click Search
Select the profile(s) you would like to link
Click the Link button, which will send requests to the email addresses on file for those accounts to confirm.
