Like I've said mate, I'm not a spokesperson for
Pinchy, although in the eyes of some I seem to have that title, incorrectly I must repeat, bestowed upon me.
Of course I'm familiar with everything you mention. The only thing I can suggest is that you write to Pinchy again, this time mentioning what appeared to be an oversight on his behalf when it came to replying to yourself. If he doesn't respond then yes, that would be bad form, but as with many things there may be reasons that you or I are unaware of. By all means you can remove yourself from writing to him, or, as I suggested, you might choose to write in the hope that Pinchy chooses to respond.
