I am switching over from a VERY unstable combo of Woo Theme's Sensei and WooCommerce. The website is having issues displaying courses properly and our clients are hitting our support email more and more everyday. Content just randomly goes "missing" until you go into it and re-save the course/lesson.
I am intoxicated by the stability and functionality of all the WPMU Dev plugins. It's like a dream come true. Everything(almost) we have needed in the past and in upcoming releases.
We sell courses based on curriculum. We also offer events that include all courses in the curriculum related to the events. In WooCommerce we did this by using Bundled Products. Are we still waiting for this feature in MarketPress or would you suggest a different solution?
