Lightstalkers

Lightstalkers is an online community for photojournalists around the world.  The main section of the site is the discussion board, on which registered photogs discuss seemingly any PJ-related topic under the sun.  The board is a clearinghouse for job opportunities, gear talk, industry news, new photography, and much more (I remember some older posts: a freelance photog inquiring about the best place to purchase body armor in Baghdad, another freelancer asking how to get tens of thousands of dollars worth of equipment through airport security, and an art show organizer advertising a call for work).  The site also features a prominent alert system (for breaking news and opportunities), a twitter-esque photographer-tracker called On the Move (for which all users can broadcast their current location), and an upcoming events board.  The greatest asset of the site, though, is the users.  They are energetic, knowledgeable, and--even in the ultra-competitive world of photojournalism--more than happy to help.
