hi..
can you not see anyones posts at all, or can you not reply to a post ?

I know that when I reply to a post it opens a new window, so if you have a pop up blocker, it could be stopping that box from showing up.

If you are able to see this, try typing a reply by hitting the "reply" button in the lower left hand corner.

Hope it works.. if not we'll keep working on it.
