Thanks for sharing your frustration with the lack of event-promotion options on Biznik. We hear you loud and clear, and this is a request we've been hearing a from quite a few other members too. So we've decided to add more ways to easily promote your event to the event tool.
Specifically, you'll soon be able to notify everyone in your network about your event with a single click (conversely, you'll be able to opt out from receiving such notifications, if receiving such announcements starts to feel like spam to you).
We're also planning ways to easily spread the word about your event to other sites like upcoming.yahoo.com.
