We've added a new Start and End date for Flat Donations in the application based on customer feedback and requests. This new functionality will allow any Experience with Flat Donations to specify any timeframe in which their supporters can make Flat Donations to their Experience - before or after their other Activities end. This functionality covers many use-cases, one precisely where users wanted to continue accepting donations on their Experience for a specified amount of time after their other Activities ended. 
 

The 'Start Date' will appear if the organizer decides to set different dates for all activities in the Basics section. Alternatively, if the organizer indicates that all Activities will start at the same time, then the Start Date will not appear as General Donations will begin in tandem with the other Activities. Alternatively, to account for use-cases like the one explained above, the End Date always shows for Flat Donations.
 

Note: The Flat Donation option and its Start/End Date fields will still not appear for Solo Crowdfunding Experiences without Perks, and the user will indicate when the Experience should end in the Basics Section.
