We'd also needs to disable the prayer time notifications that come right before their prayer time. We wouldn't want a bunch of people at midnight getting notifications.

There's also the prayer time management interface where the user can change or update their prayer times.

It would be nice to simplify it down to simply people signing up. There's a lot of work that would need to go into making that smooth.

It would be nice if the time blocks and prayer duration sections could be made optional. As far as specific times of the day as I previously mentioned, the 5 pm time not really germane to the issue---notifications we send out are emails so those could be used to coordinate everyone to be praying at the same time at 5 pm.

It simply comes down to whether the time block and time duration are visible on the signup form---ergo, it could have a default of 12:01 midnight if the time-block is invisible on the form, and prayer duration is defaulted to 15 minutes if invisible on the form. That could be accomplished through two simple checkboxes on the campaign setup, one for time-block visible and one for prayer duration visible on the signup form. If invisible, they assume the default time block of 12:01 midnight and the default time duration of 15 minutes.

It's really the sign up and the notifications and prayer fuel going out that are the need. Continuous 24/7 prayer with folks picking specific times to pray is great for many use-cases, but sometimes we just need to know someone has signed up to pray.

Great question. The prayer campaigns were designed to cover a period of time in 24/7 continuous prayer.
We're working on making it easier for people to sign up. Letting people pray flexibly whenever it works for them.

As it is now, there isn't a way to restrict everyone to sign up at the same time. I think the best solution would be to add that in the text right above the signup tool.
