I've been running into a few problems before yesterday's big outage. I'm not sure whether they are things that have been around forever, are linked to the outage or are separate.
When I finish updating a post, the screen goes to the list for the subforum that post is in - say "investor alley" (although this happens with any subforum). While I am in the subforum, I check out posts marked "new" to see if there are any interesting ones. Sometimes, there are posts marked "new" which were last updated a week ago - and that shouldn't happen, because each day I mark all the ones I don't read with "mark all read" when I go through them. Also, sometimes when this is happening, I "reload current page" with the browser and different posts are marked "new".
