The List of subscribed threads in MyFT?
 

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.

Its based on posted since you last logged out. Note if you are having troubles with your FT cookies showing what is read/unread then this affects subscribed threads equally as unsubscribed ones.

But what if I don't log out? Logging out and logging in definitely resets the list, but if I never log out there seems to be just plain randomness in how the list gets truncated from my experiences.

Don't sessions time out eventually? At least they do for me after somewhere between 30 and 60 minutes (sorry - haven't pinned it down more precisely).

Yes sessions time out and 'new threads' are reset after 30 min. of inactivity.
