You seem to be replying to your own posts. Very often there seems to be sequential posts from you on the same subject with no intervening posts from others on the subject. Not that there is anything wrong with it! Maybe it's just my desire for exposure to AB "technical factoids" rather than having to ripple thru non-AB related opinions and diatribes. Of course I might just be getting old and crusty. Yeah, probably the case.
