This Saturday, September 20th, people everywhere are getting together to celebrate free software. Install parties, encryption workshops, hackathons, you name it. Here in Massachusetts, FSF Web developer David Thompson is running a getting-started workshop for F-Droid, the free software app repository for devices running Android-based operating systems like Replicant.

Wondering what to do for Software Freedom Day? Take a page out of Dave's book and share your favorite free software application with a friend. What better way to celebrate than exercising freedom 2 of free software's four freedoms with your community? If you're on GNU Social or Pump.io or even Twitter, tell us (@FSF) which application you're sharing with the hashtag #SFD (see our thoughts about Twitter).

This is the eleventh year of Software Freedom Day, and people are holding events in almost 100 countries. Thanks, everyone involved for reminding us how active, creative and inspiring the free software movement is. However you choose to celebrate, have a great Software Freedom Day!
