if u like the thread and all the replies and u wanna save them, how can we do that… can we do that 
:) Not certain if this is what you are asking about, but you could try e-mailing that thread to yourself. In all threads, you will find an option of e-mailing that thread to someone - it's located in the middle towards the bottom of the thread. You could e-mail that favourite thread to yourself - so in a way you never lose its URL and you could always revisit it when you wanted.
i hope that helps, (but sorry if this is not what you are asking about).
Emailing will send the link to the email address. If you want to retain the whole thread, select all the posts in a thread (using your mouse), and copy-paste to a Word file. Viola! :)
wow we kool
thank you
Sorry! 
Faisal Bhai is absolutely right, that would work far better.
but don’t u guys think there should be a way to save a thread on your PC… other then that
