The RSS feeds are not adding page or post hashes for the most recent reply and they contain no content. This doesn't make for very user friendly output in an RSS reader.
Can easily replicate comparing "Latest" link in a form main view to top link in same forum's RSS.
I recognize that the philosophy here is not to deliver content through external methods, but a partial glimpse of content in RSS would be very helpful....to avoid opening a 15 page thread at the beggining, bounce to last page just to read a mundane reply of little value. Control of content output should be an admin option
