I'm curious the logic behind this feature... If in fact its during the great Tribulation, the last thing i'd want is to give away my position..
What is the source for this data? (sounds interesting overall)
Sure sounds good.
I think there should be a control option for the popups as well.. (ie simple way to turn them off in the gui)
Perhaps a new tab on the options screen?
Well its sort of a multi-use feature. Im thinking of having people store their nickname, long, lat (of street corner) and Christian testimony in the chain, and optionally e-mail address and BBP receive address (using a Contact Card - Add feature). This would allow us to send/receive to each other by nickname or email. And read others Christian testimonies.
The idea behind the great trib feature is if the rapture occurs, the idea is a user could go to our map and find areas of light (IE other biblepay users) to camp with.
If you want to add a checkable option, sure, you could add it somewhere in the settings page, what about in Settings | Options | Wallet as another checkbox? If you want a new tab go for it.
