That won't work across time zones though.
I'm in Australia and see times in my time zone. Many of our members are in the UK which is 9 or 10 hours behind. What I see as September 13 19:00 would show as September 13 10:00 in the UK.
Our members liked the Post Number plug-in but if doesn't return I won't be upset. I see how the numbers change after deleting, hiding, splitting posts. The PostID idea is interesting but I can't see too many members quoting numbers like this - 2931519 (a real post number from a few minutes ago on my Forum)
With collapsed quotes, we'll just keep educating people on linking rather than saying "post 1234"
Now, about the old Automatically hide/delete inactive posts feature......😮
