Hi Eve. There are a few options that I've used, depending on the customer's needs.For example, if a customer wants to review a text and graphic-only module, you can print it to a PDF and e-mail.For modules that contain voiceover and/or built-in interactivity, I've published to HTML and posted on my server so the client can review via an e-mailed hyperlink.I've also published to a single file executable and e-mailed the file to the client. This is useful if the client, for example, wants to review it while flying somewhere.So the answer to your question depends on what's easiest for your client; be flexible and offer whatever he or she needs!Best Regards,Dave
