Unless I scrambled my brains at Six Flags with RhondaS today, what you actually email is just a link to the page in question. Once you click on the link, you are taken to the page and you can navigate around like you always do.
When a "thread" is revieved via email, the first page will open then the recipient can simply "click through" the remaining pages on the thread. Just like you would normally do on the boards GrammieMame.
