That's the Programmers' Club, not the Programmer's Club. The Programmers' Club: the Club of Programmers. Read all about Plural and Possessive -- but of course you already knew that, didn't you?
ProgClub is a club for computer programmers. You can read about what we do or get up-to-date with our news or our blog. Then you can read our terms and conditions. Then you can register. Then you can have some fun using our member services, participate in our forums, and contribute to our open-source projects.
Every programmer needs a good club!
