I figured out how to email through, perhaps. If your reply-to-email to the videoblogging group has all the html stuff on the side bar that Yahoo sticks on the email, such at the "recent activiy" side bar, colorful "sponsored links" etc, then I guess the email will get clogged up while Yahoo checks and delivers this back to the group.
If you just create a regular email or copy and past the text, it should work faster it seems. . . .or perhaps only take text emails.
