Hi all! I'm a Fellow of FSFE, too. Let me add that, as vog already mentioned, the Fellowship is open for everyone. I was told that FSFE already has some Fellows from the US. So you are not alone if you join FSFE. :-)
Of course some of the really great thinks of FSFE are the local Fellowship meetings, etc. which is more easy to organise with more Fellows around. But I would love to see Fellowship meetings in the US (usally 2-3 Fellows are already enough if you invite "non-Fellows" too). But all this is not mandatory to join FSFE. There are als FSF members at Europe without any FSF or LibrePlanet meetings. So the other way around would be perfectly OK too.
One example would be the Document Freedom Day: documentfreedom.org
