Thanks for contacting TypePad One customer support! We've reviewed your request and have responded to your ticket 'twitter'.
Hi John-
Thanks for your patience. We released an update to TypePad today which now allows Guest Authors to share posts on Twitter, Facebook, and FriendFeed.
The Authors can add their accounts at Account > Other Accounts and select to share their posts. Then, the sharing options will display on the Compose page.
Authors, however, will not have the option to set the sharing options as selected by default.
Please let us know if you have any other questions.
Thanks,Jen
I wasn't expeecting that sort of response from Typepad!
