PIG, the PHP Interest Group, is an ICQ interest group. PIG was created to gather people who use PHP and ICQ so they can be sure to always have someone on ICQ they can turn to for help. This is especially useful if you have a deadline to meet with a client and can't wait for responses from a mailing list or Usenet.
