My thinking on this is... I couldn't promise not to respond to someone's posts just for the very fact that I can't remember such details! I don't look at who is posting to begin with, and usually only catch the originator's s/n to fine tune a reply. I take postings at pretty much 'face value' and do not insert history nor personality of the poster into my answers. That could be a poor way to do it, but "face value" is definitely the only way I can go with this.
