My team is in need of Mac users who meet all of the following criteria:

• use their Mac at work for at least 20 hours per week
• use an email application on their Mac (such as Entourage, Mail, webmail, ... )
• use a calendar application on their Mac (such as Entourage, iCal, or a web-based calendar)
• use an address book application on their Mac (such as Entourage, Address Book, or a web-based contact manager)
• live in the San Francisco Bay Area, and are available the week of 22 June 2009 for a 2-hour usability study in Mountain View

If this describes you, please email uccoord (at) microsoft (dot) com with "Mac" in the subject line.

If you're a Mac user but don't meet all of these criteria, my team is conducting lots of research in the upcoming months. The majority of our research is conducted in either the Puget Sound or San Francisco Bay areas, although we do travel around the US and around the world to meet users in other locations. You can sign up to be notified about future Mac studies in your area here.

Edited on 6/17/2009 at 6pm: I now have all of the participants that I need for this study.  You can still sign up to be notified about future Mac studies in your area at the link above!
