The new site has unfortunately made using PM's as a method of communicating to groups a little more awkward than it used to be, and haven't addressed issues with them that have always been present.
Firstly, as an actual bug report, PM's now don't return to the top of your inbox when someone posts in them. Which means if you don't have the "notification" on your mail icon, then you have to trawl through pages of @replies and such to find it.
Secondly, why do PM's no longer state WHEN they were posted? It was kinda useful to know whether someone replied in the PM 3 minutes ago or yesterday, if there have been multiple replies since you last read it.
And lastly, would it be possible to make PM's open on the last page? It seems silly to have to read the first page of a PM every time you get a new response to it, just to get to the last page where the new post is. Especially as the next/prev page buttons have now been relegated to only the bottom of the page... (This last one isn't necessary, just something I thought would be awesome for a long time now.)
Thanks for any response this gets.
