Hi Victoria,
Just reading your question and although I can't help you, I think you may be able to help me if possible.
You mentioned in your post that you can set a seminar so that you can sign up as many times as you want, how do you do this because at the moment my company have courses set up but once a member of signs up and completes it they cannot be added on to the course again? So for example if they wanted a refresh a few months down the line I can't add them on to the course because it comes up with a warning that they have already enrolled.
Any help would be great I am new to the system and trying to get my head round it.
Kind regards
Kerry
