Last week I was invited to become an observer of Free Software Foundation Latin America and I did accept.
Observer are not meant to do much, basically track the mail list (one more, oh god!) and provide feedback, getting used to their work flow so maybe you can turn into a more useful member if required.
"But you're hacker, WTF you'll do there, waste your code time?" you may ask (I asked that myself). Well, I'll try to keep focus on SW-related things instead of political issues I really dislike. FSF is about software in the end, and one of the few organizations that have some power to help us hackers... just hope that discussions were like those technical I was used to :-(
