LinkedIn is a career networking site where you can create a professional profile, make connections and keep in touch with current and past coworkers. By creating a profile with your job experience (which can be continuously updated), you can easily download a pdf of all your information formatted as a c.v., which can be sent to prospective employers. Another bonus of the site is its networking capabilities, allowing you to meet and keep in touch with others in your field.
The Art Therapy Alliance is an online professional group about art therapy on LinkedIn, and a great way to become involved in the online art therapy community. There is a message board for posting discussions, and Gretchen Miller, MA ATR-BC, creator of this group, also puts out a quarterly news letter. The news letter includes a list of other art therapy online groups, upcoming events and workshops, art projects made by group members, member news and more.
