name when clicking link to join

I have a Basic account of my own. I was the host of a regular weekly meeting for 6 mos and signed in using the group owner's administrator account. Now, when I click on a link to join a meeting, my name shows as that group owner's. When I join a meeting through my own account and the mtg ID and PW, I show up with my own name. How can I get rid of the other name so I can just click on links to join?
