The subscription feature is broken.
New posts in subscribed threads are not showing up in the normal subscription page, the "Your Posts' Section shows them but not the subscription page itself.
I usually just go to My Account-->Subscribed Threads. It's almost always up to date. There seems to be a delay on the "your posts" button near "new posts" anyway.
Shouldn't you be able to set it up so the forum clears it's own cookies and cache when you do these updates? This happens every single time there's a major update (never the same problem either it's always something different)
