Anyone interested in learning about and contributing content to a new website about all aspects of Tucson is invited to a planning meeting at 5:30 p.m., Thursday, Aug. 15; free. The project, which arose from a recent Code for Tucson weekend, creates opportunities for people with Tucson knowledge to share it, and for others to discover new insights by following threads of interest. The meeting will include a demonstration, and time for audience suggestions and requests. Reservations are requested; visit "Tucson Wiki Meetup" on Facebook to register and for more information.
