Short phpstorm install+tutorial to teach how to link it to Apache and how to debug code in a small running session.

http://www.jetbrains.com/phpstorm/

Who will lead it, from the present or remote attendants? Robert Plummer will guide it, remotely, through BBB. (http://tiki.org/Live)

If nobody present knows about phpstorm, this can be replaced by discussing favorite or alternative methods for debugging Tiki when the real logic is hidden behind abstraction layers or MVC or ajax webservices.
