The setup: Multisite with several "child sites" where the users on the child sites can post blog posts(!), posts that via FeedWordpress enter the mother site´s flow of posts in the loop.
I am searching for a plugin or a function that allow me to "mash" the posts from the child sites into a calendar widget (when child site users post within a given category).
I want the calendar widget to be "all WordPress" meaning I am not looking for yet another Google Calendar feature.
Any suggestions? =)
