Capturing a portion of the the screen when using XP, IE8 is it possible?

I have tried using the snipping tool of Paint but it doesn’t seem to register that. For example, if I just want to take a screenshot of the first few question in Fluther homepage, it would give me the screesnshot of the whole screen.
a)If it is not possible why is there nothing that says that it is not possible, as soon the snipping tool is clicked?
b)How do you go around it? By the way, it is going to be attached and sent in an email.
