I'm not too familiar with the Boston market. You might check on wesites like meetup.com. Also, twitter is a pretty good way to meet and keep in touch with local tech communities.
Can anyone recommend SQA Forum to join or SQA user group in Boston area? Office is in Boston. Interested in following topics: Selenium WebDriver and UFT automated frameworks, agile testing, mobile testing non-apps (browser based websites on mobile devices).
