Terry> Even though such is standard for the majority of web fora?
I participate in a couple different web forums (914s and swimming). Both present their topics in chronological order and provide a link at the top of every page which jumps the user to the first unread message (no matter how many pages there are in the thread or where you happen to be at the moment).
Reverse chronological order is a nightmare for anybody trying to bring themselves up-to-speed for the first time on a long discussion. In my mind, the only place where reverse order makes sense is in cases where messages rapidly become less important as they age. Think following the Japanese earthquake/tsunami aftermath.
