Thanks for the feedback; I feel like this whole event was handled entirely reasonably by all parties (of course nothing bad happened so it might feel less reasonable if something bad did come of it)

The original post is heavily modified from the first iteration. look at every explicit clarification of things and simplify it to one word. i.e. It has given me cause to have some concerns arising from you finding it useful." used to read, "it concerns me that you find it useful". which when read wrong is really not a nice line.
