Has ordering of "My Profile" changed?
Right now as I look at my profile, they are not in "most recent" order. I don't think I changed anything. The first one is 16 minutes old, the second one is 2 hours old, and the third one is 22 minutes old.
As of last week, you're now able to sort the discussions in your profile in three ways: By Date Started, By Number of Replies, and by Last Reply.
If you sort by Number of Replies, you'll only see discussions that have been updated in the past month.
These are the same sort options that exist on any board page on the site. Click any of the options to switch your view.
