Awarding due credit...?

Hi all. Me again with yet another annoying query. Recently, I have purchased full-perm bits, props and pieces for purposes of including them as elements in some commercial builds I'm developing. Each one of these various bits and things contains the advisory that it's OK to use them in commercial builds, and I try to be careful in that regard so I don't take unethical advantage of a creation intended for free distribution. What would be the best way to render acknowledgement to the creator of an element that added that last perfect touch to a build you can charge big Lindens for without cutting your own throat commercially? Considerable work and talent went into the creation of these things, and it's good karma to give credit where it is due. Thoughts, anyone?

That might be a good idea .You could create a notecard giving texture credits by name.Just inlude that with your landmark.job done.
