How can i see the latest posts in forum?

actually, the forums don't seem to be refreshing even when i make a post now. my last post to this particular forum isn't showing up after refreshing my browser. however, when i look at the list of all the forums, it shows that i made the last post to 'the pub, feedback and announcements.' when i go into that forum my post isn't there!!! i've tried using 3 different browsers on two different computers using 4 different ip addresses and still the same thing!!
