I checked out that link but have not worked with files stored within My WebEx. Someone else may be able to chime in here. At first blush, it appears to simply be a place where you can upload/download files to your personal WebEx account. I do not know how you would have other users access files within your My WebEx folder structure (if that is what you were thinking). I can tell you that within our organization, we only send the WebEx session invite to one person - our training coordinator - and she forwards the invitation to everyone who has enrolled in a session (she obtains a roster through our LMS). In her email, she includes any pre-work documents (or directs people to our Intranet). This is how we ensure people see, download and pre-read items in advance, while also getting the WebEx invitation/link. Thus, we do not use WebEx for registration - that is done through our LMS. I realize that may not work for you and you need/want to utilize the registration capability within WebEx. I still think, though, you could follow a similar workflow, if users register with their email addresses. You can obtain a list of those individuals prior to session and send an email with documents/pre-work. It is an extra step for you, but it depends on how important it is that attendees get the material in advance. sorry if this is rambly - just trying to assist if I can.
Best,
Eric
