I would like to suggest a new plugin be developed for multisites. With the arrival of Google's Hangouts on Air, it's all the rage now to do "webinars" using Hangouts. In order to justify moving away from expensive services like Go To Webinar, plugins are being developed to give most of the functionality of those other services and be able to set up the webinar inside our WP dashboard.
I haven't bought one of these plugins yet because they are not multisite compatible. Here seems to be a good one: http://hangoutplugin.com/
Can you please pass on this suggestion to the appropriate developer? This would be such a fantastic addition to our arsenal of plugins to both use for ourselves and offer to our Prosites upgraded levels.
