I don't know if this is the best section to ( ask questions ). So, excuse me.
It's my first topic anyway, and I couldn't find any other section to ask for help.
I believe you don't need any explanation about my problem, but here it is anyway:
John just started a topic at a.html, while Sandra navigates b.html,
I want some solutions to let Sandra knows about John's topic at once.
Could that be happen?
Notice: We're talking about 2 different pages at the same directory in some site.
Any help will be approciated!
I mean please help me !!
