the point about the exposure issue (sorry rifleman, but that is the cooect word) is that it should be up to the copyright holder to decide if the exposure is worth a loss of immediate revenue or not - not a fan.

sometime it is, but not always.

there are two youtube montages that use my work without my prior permission. in neither case did the uploader quote me as the writer.

I was able to add my name in the comments (or someone did it for me) so I let them stand, but it would have been better it the system had required the poster to input my name. he might have decided to ask me first.
