First, please send everything — both comics, and comments intended only for me — to this address:
If you use any other address, I might or might not ever see it.
Also: The complete left sidebar still does exist in this new template: Look to the left, where the sidebar just says COMICS I DON’T UNDERSTAND followed by “Home” and “Your Random Comments.” Above COMICS I DON’T UNDERSTAND, to the right of the three horizontal lines, is an icon that looks like a folder. Click that, and the full left sidebar will appear.
I know. This is counter-intuitive at best and borderline insane at worst. Presumably, somebody thought this was a good idea.
Many of you have already figured this out, but understandably many have not.
Comics I Don't Understand 
I appreciate that – it never would have occurred to me to look there.
Web designers be crazy. My local public library network (Hennepin County, Minnesota) recently redid their website and removed all of the library book sale information from the “events” list/calendars, on the theory that said sales (of which there are many many many during the year) are run by individual branch’s Friends groups, and therefore they “should” be buried a couple of levels down under the Friends of the Library “join up” plea pages instead, three or four clicks away, with nothing pointing confused buyers there — apparently it’s considered intuitively obvious. Right.

You beat me to that, Arthur!
