Currently, I do have an organization account with a certain pricing plan. I am curious to know, how will my pricing plan affect when I associate a few new users to my existing webinar's account.
Typically if you change your subscription type online, then there will be a calculated, prorated amount subtracted from the new plan total. Pricing should be similar to the current offers here: https://www.gotomeeting.com/webinar/pricing
If you add additional organizers to your account, then the price will go up.
If you have one organizer listed on your account now and you add two more to create a plan with three organizers listed, you will then be able to host three separate GoToWebinars at the same time.
With three organizers, the price will be about three times what you are paying now. Only LogMeIn can tell you the actual price.
