Thread exclusion not working

**** I goofed with the title, it should have been "Latest Posts filter not working" or something. ****

I have the Playstation Chat forum ticked under my "Latest Threads" exclusion options, but continue to see it.

EDIT:
Any chance we can have the private clan forum threads show up under the subscribed threads?

I wish you only subscribed to threads that you select, instead of the other way around.  Right now we are essentially subscribed to all, and we eliminate categories we dont want.  Why not just start with no subsciptions, and make it manual.  A button on the top of the thread that subscribes you to that one. 

As of right now the Subscribed threads column on the left is more or less useless for me.

That's not what I'm referring to, Durban, sorry for the confusion.

I meant the option to select which sub-forums you wish to see on the Lateat Posts page.

@Savage - everything I've checked tells me this should be working for you, let me know if it's still not.

As for the private clan forums in there, it's something that's excluded for performance reasons.  If there's a huge outcry I'll reconsider, but for now, sorry.

@Durban - in the User CP have you unchecked 'Automatically subscribe to threads I reply to'?  That should do exactly what you describe.
