Ok, ok, ok... I understand how they work (i.e. how to subscribe, unsubscribe, the order they're in, etc)...

But I don't understand how it is determined to "cut" the list display in MyFT... Sometimes the list clears itself within an hour. Other times it's multiple hours and I have a long list of threads to scroll through to get to my subscribed forums.

Is there a general rule for which subscribed threads are displayed in MyFT? By time? By login? Random? If the thread has been read?

I've done some testing and I can't figure it out. Any ideas?

Thanks.
