As a member of TUG, the TeX Users Group, I recently received an email about a new membership drive in hopes of reversing the trend of a slowly declining membership. I know one can learn more about TUG on their website and can read the membership form online. I also know that I enjoy reading TUGBoat, the journal that TUG produces as it contains interesting articles about things one can do with TeX as well as articles about typesetting and fonts.
What are the other benefits of joining TUG? (That's my official question; this post is really a not-so-shameless attempt at bringing awareness to TUG in hopes of increasing its membership. Frequent users of this site should be interested in joining.)
