bearisgray, i understand your embarrassment. in an email, it comes as a surprise. it shouldn't.
i think that the problem here is that the risque-ness comes out of the thought in the general thread. but at that point you could say " please go to CC and see "WARNING: How to cut perfect HSTs to continue". some people will be too lazy, some will want to catch the rest of the original post, and some will move over. in any event, it would die a natural death for lack of enough interest, and other posters should not be offended. it's the WARNING part that's important. when reading GCC you may skim over the title and keep going.
