Apple’s User Group Advisory Board, in association with Macworld Conference & Expo, has announced two opportunities for members of Mac User Groups (MUGs) to attend Macworld Expo in Boston for free or at discount, depending on the conference package you choose. MUG members can register for a free exhibit hall pass or take 15 percent off all conference packages. The specials–available only to user group members using a User Group Priority Code (which has been e-mailed to all Apple-recognized User Group leaders)–are available through May 7. Macworld Conference & Expo—Boston 2004 will be held July 12-15.
