It is about 0600 GMT right now, and www.rangefinderforum.com is not responding. Possibly a server problem or something similar.
We had a problem a few months back with Dennis Lohmann's www.eazypix.de website with his extensive listing for Minolta ROKKOR lenses, but it was traced to a very simple oversight. That was easily cured, and it is back.
This is a problem that is of some concern to me. Things that are stored only digitally can be subject to sudden loss just by a power line problem for a moment. There is still merit in having a "hard copy" or paper printout of data files for long term storage.
