It may be somewhere already, but if not it would be great if there were 'latest 24h/3days/7days' options that included all forums. I tend to dip in and out and would like to see all forums in one place rather than have to go through them one at a time,
I subscribe by RSS to each of the forum threads (in Safari), which then gives you options to view by day, last 7 days, last month etc. A quick search will help you if you're not familiar with RSS and depending wich web browser you use.
Thanks for the tip on viewing by date James. I also like this!
