I realize this forum style now has mobile capabilities, but people still ask for Tapatalk support, for various reasons, including its ability to send push notifications to users' mobile devices. Unfortunately, I'll even look into paying Tapatalk monthly money for the privilege of not cluttering our forum up with "Posted using Tapatalk" signatures.
We already thought of this app thingy (android based however), but unfortunately I am kinda have my hand full with real life matters. We have also posted some of useful links if someone out there wish to pursue with this (I forgot the links though, lol). Json was the answer to get data from and to the user for the intended notification. Of course, some table need to be created to store and retrieve that data.
