But then when I try to post (by hitting the "Quote" button), I usually have to log in again. I get the message "You are not allowed to reply...." or something like that, and I see I am "Guest" in the top right corner.

But, again (same as Marmite's post above), it worked OK with your post. Maybe DD's done some tweaking?
