I have had quite a headache with your recurring events facility.
The great thing about events+ is being able to create recurring events and then seeing separate SKUs created when linked through the Marketpress plugin.
Here are some issues that that are occuring because I am doing something wrong or that need urgent ironing out by the WPMU developer team:
I can create a recurring event for, say, every Friday for 3 months. And if I want the event to not be available on the last Friday of every month, I can go to the "Edit instances" link and cancel or close that instance.
But if I go back into the root event because I need to change details, and update the event, that instance that I cancelled or closed is republished as a live event again.
Hell of a headache if you set up a daily recurring event for 6 months, close 8 of them, and then need to re-close them again after editing something else in the event.
RECURRING vs. SINGLE EVENTS
If you have set an event as recurring, and want to change it back to a single event, there is no option to do that. You have to trash the event and make it again from scratch.
USING PRODUCT AS ADMITTANCE
Great idea to have this. It means I can give people coupons.
BUT, every time I edit an event, like change details in the content, and update it, it does not "remember" that I assigned it to that product. It needs to be reassigned to the product every single time.
