the software i am developing is called pilotride.com
see the web site. its one big difference is the software is designed for flying clubs and FBO's that rent aircraft. this is NOT a public free for all where someone posts a flight and the world sees it. this software secures all rides and members data to the club or FBO.
i am creating software for just this purpose. please see the software page at www.pilotride.com
please like the facebook page if you think the idea is appropriate for your needs.
