You know what I have actually sussed how to clear the long list of post we all seem to be getting.
You need to click on each thread weather they say updated or not then check the top of the post on the right where it say's total post 123, new 1.
If it say new 0 then it wont make difference but some will say new 1 or even more,
Hope this helps I know we are all rather fed up with it.
Kind Regards BB xxxx
