I just got back on since last night.
However that's one of the things that was happening to me:
If I managed to make a reply, it wouldn't show up in the recent list.
But then if I got logged out it would show up.
Log-in----Gone again.
Log Out --There is is again.

Hmmm, seems like maybe a session plus caching issue.
Translation:
When you log in something called a "session" is created and information is stored in it.
Caching is where the site will store commonly hit information and have it stored in memory (instead of deep down in the system) so that when another request for the information occurs, the info is already there and can be served up super fast without involving the deeper parts of the system.
When you are not logged you have no session info (usually) so your visit is more like a clean slate.
When you DO login well your previous session info may be hanging around and making things look/feel like they were in the past rather than in the present. Hence not seeing new things.
Somehow old user session information and new request caching information seem to be out of whack :)
This is just a guess since I don't have any supporting evidence but maybe a system guy will read this and look in those areas of performance :D
