This is my question. I have a login for a user. Many users can log in with same credentials. When user/s log in, they see a set of radio buttons. Lets say `User A`, `User B` and `User C` log in at the same time. When `User A` selects some of the radio buttons, `User B` and `User C` should also see them selected in their pages. (and vice-versa) If `User B` changes a selected radio button again, `User A` and `User C` should get that updated value in their pages. Like this most recent selections should be visible in all pages. Please help me solve this.
