Comments are great, junk isn't.
The few who have commented here will notice it takes a while for them to come up. Appy-polly-logies, my droogies, for delaying your horrorshow comments (I believe that's how the young speak nowadays. I read it in a book. The village children still use 'gadzooks' and call each other 'poltroon'. We're a little behind the times here, and they have not the dook of an idea how to comport themselves in public, O my brothers. I, however, am more in tune with modern parlance, as you see).
For every real comment there are at least fifty nonsense ones. If you have commented and it never appeared, it might have gone into the 'junk' folder and been deleted. I can't read them all because whenever I go there I see a few hundred built up and delete them en masse.
So if you commented and it didn't appear, feel free to try again.
Except you spammers. For you, feel free to drive nails into your own heads and then heat the ends with a blowtorch.
If you're unsure quite how to do that, come and visit. I give lessons at reasonable rates. First session free.
