connecting people

Is there a way to connect people though your app. For example if someone leaves a comment in your app then someone can go into the same app and see that they posted a comment??

hello, I do not understand, you say that in any application? or made ??especially in codea? or in a code made???

like kind of what we are doing right now how can you do that in an app @luismi

Probably an HTML request to a private server that pulls data at constant rate to update it, but you need quite a bit of skill
