You're not alone. There are a number of RFF people on flickr: ljonas, Roman and Justin Viiret. I'm there under the same ID (Sockeyed).
There are some good groups to join, too. I started the Rangefinder, Russian Cameras and I Shoot Film groups, and there are also Voigtlander and Leica groups.
It's a very well-designed site and free to use (with certain limitations). If you get a 'pro' account (which doesn't cost much), you get nearly unlimited uploads.
