My site was started 13 years ago, with the the very first forums added to the site almost 10 years. So, in just 6 weeks time it will be the 10th anniversary of my site's forum. (for this interested, phpBB -> vbulletin -> xenforo ) Interested in some thoughts and ideas on how to mark/celebrate such an auspicious milestone with the site community? How would (did?) you celebrate it?
