Well my Yahoo Inbox has 4472 messages in it, but none of them is unread. I assumed that tinners' 110 was unread msgs?
Quite right, although some of them are messages I've read and then "marked as Unread" (and the others are things that I know what they are, don't need to read, but for some reason don't yet want to junk). The total in my Inbox is around 600.
My email set-up is rather like my desktop vs. My Documents set-up, actually. I file some things and keep others 'visible', and it's not necessarily the case that the former are 'done' and the latter 'still to be done'; it just depends whether they fall easily into a 'fileable' category, and also whether they're things I want to see and be reminded of regularly or not.
