I've added two more applescripts which allow for the transfer of entourage tasks and notes to your OF inbox. Along with the messages one, this should hopefully complete the "entourage suite" :)

FYI, if you haven't seen this yet, Omni wisely broke out the applescript threads into a separate OmniFocus Extras sub-forum, so once we all start using it, all future updates will be over there.
