Apologies..off thread
The evidence seems to be mounting that there is some form of problem with the "thread that cannot be mentioned".
There is a roundabout method of getting into the posts but as has been said, if you are successful and then try to go into the Private Flying Forum logged-in, you get slowdown/lock-out. To fix this, logout to clear cookies.
Good luck Pprune peeps..it seems that you are under attack...I wonder why...?
