Design 3: Calendar
In order to find a babysitter for her children while she goes on a date with her husband, Lia opens up SitterPlan and looks at the weekly calendar of babysitters' availability. She checks off the boxes to show her top two sitters' calendars - Jennifer and Wanda.
Lia decides to go on her date on Friday, from 7 to 11. Jennifer's not free during that block, but Wanda is. She clicks the part of the calendar representing Friday at 7, which pulls up a (movable, closable) popup to create an event. Lia chooses to share the event with all her babysitter contacts - if Wanda ends up having something come up, it would be better if the others have had time to think about whether they can be free - and
clicks POST.
Wanda sees the job posting the next time she opens SitterPlan to check up on her part-time babysitting business. (Probably she's configured SitterPlan to send her emails when someone posts a job. Like Facebook, but less annoying.) She sees on the calendar that Lia has posted a job on Friday, when she's free. Another family has also posted a job on Friday, but Wanda prefers babysitting for Lia.
Wanda clicks on Lia's job to pull up a popup that lets her apply for it. She enters the amount of money she'd like to get paid for the job and clicks APPLY.
Lia gets an email with that information. She can reply to Wanda immediately to set up details, or wait a few days to see if anyone else replies before choosing someone.
