In fact if the use of RED for charge derivation is the recommended way to go with generating charges for the AMBER force fields, which I assume it is since you and Piotr developed it together, then really it should be better advertized from the AMBER site and in some ways integrated into the AMBER tutorials slightly better.

It would be great to have a tutorial on the AMBER site that shows how 'modern' charge derivation should be done (at least in an introductory fashion) in a way that couples it in with building a system from scratch. It can then of course include links to more complex examples / considerations.

I think the R.E.D. license is completely incompatible with the
AmberTools license. Of course, people who write software have the
complete right to put whatever license they wish on their work
product, so I am not complaining about that. I just think the
AmberTools project is in the best tradition of academic research and
would like to see it promoted, but R.E.D., based on its license, is
not working toward the same end. In my opinion, of course.

At some point somebody just has to bite the bullet and make their best attempt to put together something that will be useful to beginners.
