We're looking for a plugin for Wordpress that enables registered users to submit events to our Google calendar.
Events will be approved by an admin (with option to change that moving forward) and anyone with a registered password will be able to submit an event by entering info into pre-defined boxes (time, date, location, etc - see attached pic for reference).
Events submission should facilitate recurring events and should save venue information to avoid having to enter address, phone numbers, etc on multiple visits.
Spam filters should be in place to prevent spam postings
