Hey, it just happened there when I tried logging out (as it has done before) instead of the forum I got a message page thus:
'Server not found
Firefox can't find the server at
www.metamatic.com.Check the address for typing errors.
If you are unable to load any pages, check your computer's network connection.
If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web'
I'm back now after 3 or 4 attempts to either find the metamatic homepage, or having done so, having to do the same to get to the forum.
