Reocurring Webex Webinars & Tracking Registration

We are working on possibly having three different reocurring webinars that will happen bi-weekly or once a month (depending on which wbr it is). We will run these through Webex.

Is there a way to just capture the registrations each time? I don't want to have to have a program for each, etc. I just need the registration information.

Thanks!
