In the mod library the same person who made the mod that affects the home page also made
another mod that affects this page:
http://www.lemmingsforums.net/index.php?action=recentYou can currently get to that page via the icon next to the "Recently Updated Topics" text on the home page bottom section. Without the other mod, right now it still lists recent posts rather than topics, but sounds like with the other mod, that might partially address what Simon and NaOH ask for, at the cost of an extra click to get there.
[edit: to clarify, merely changing the number of items shown on the home page section from 10 to something else is just an existing setting in the theme that the admins can change. I'm pointing out this other thing because it sounds like whatever number we set may still be too low sometimes for some people.]
To be honest it never occurred to me that people would want to see 3
+-day old topics. I'm genuinely curious at how people intend to make use of such an ability. Is the intention for being able to catch up after multiple days of not checking the forums, or are there other needs in mind?
