Luther, God Bless you and thank you for taking up this question, and bless you even more for actually being able to answer it--

I hope that you all appreciate that he has gone to a great bit of trouble to make clear, in writing, a very important musical idea that many of you were either A)not clear about B)Were mis-applying, or C) Completely misunderstood,, and that some of you had actually payed good money for someone to teach it to you (either in music classes or music lessons) and still hadn't gotten it right.

My two cents(I always have something to say) is that part of the reason for confusion on this point is that people confuse the explanation of what the guitar chord notation means with the theoretical explantation of what is happening in the music.

"Csus4" is not really a chord name, it is a description of a kind of harmonic movement that is happening horixontally in the music, but it is also convenient to use that name to describe the guitar fingering that is used when that kind of movement is happening.

It is entirely possible to use that same fingering(or the combination of notes, say "C-F-G" that goes with it) without having the "suspension/resolution" occur--
