As recruiters, it is important that we become familiar with websites representing professional associations for positions that we recruit. For example an IT recruiter should be familiar with HDI (http://www.thinkhdi.com/), the Association of Information Technology Professionals (AITP), Women in Technology International (WITI), etc. If you specialize in Enterprise Architects, then be on The Open Group for Enterprise Architecture Forum, etc. These sites provide valuable opportunities for broadening your reach in the business community and getting to know the group's members, many of whom will be qualified job candidates. Often these sites will also post job openings for a fee.
