I'm a little confused here, so I'm going to ask some very elementary questions (and the photo.net link didn't work for me, so I couldn't gather anything from there).

How does the flash attach to the camera? Is there a cable or is it a wireless/slave flash? If wireless, what triggers it? Is it optical? Radio? Something else? If it is not optical (using the camera's built-in flash), does it come with some sort of transmitter that attaches to the camera?

If it is optical, does it have a means to ignore the pre-flash from the built in camera flash and fire on the 2nd flash that happens when the camera shutter is open?

If it is operating as a slave, does it have any provision for controlling the exposure? Does it somehow rely on the camera's ettl system? Or do you have to run everythihng in manual mode with the flash?

Does the flash have an instruction manual with it? Does the manufacturer have a website?
