Darn it, Russ! Be careful with your wording. Some folks will consider 
you an authority, so you've got to make sure they get the right instruction.

For those other than Russ, who knows this full well, USE is a separate 
right in copyright law from the creation of derivative works.
You may USE GPL software any way you like. There is a significant rule 
set regarding the creation of a derivative work, that you should 
understand before making one.
