Can anyone offer me assistance with Adobe eLearning and building an Asynchronous Webinar?

Captivate could be used to provide recordings of webinars, but isn't a platform for providing actual webinars...

So if you gave a webinar using applicable tools, like Connect or WebEx or such...and recorded that webinar...you could place the video recording in Captivate and add a variety of components (slides, bullets, effects, interactions, etc)...though Adobe Presenter may be better suited as I believe its sold as more a Connect companion...

What are you trying to achieve? Do you have an actual webinar platform already?
