There is a shared (google) worksheet in which multiple users edit and watch simultaneously. For those who have used the shared spreadsheet google knows that when someone starts to write everyone sees in real time. Anyway I build a program with some extra functionality to replace this shared worksheet (I used python 3.x and tkinter) The problem is that I have no idea how to put this program online for multiple users (at most 120) to use simultaneously. P.ex: someone started typing something and everyone will see (same as the google worksheet). If someone who has understood the problem and can at least guide me what I should research / study, I will be eternally grateful!
