Good except for one category ('plum') which struck me as a bit weak.

Ha! Thanks! :) Glad you enjoyed it because I have enjoyed many of yours, Wolfdog.

The 'plum' one is actually one of my favorite parts of the puzzle*. The only thing is those kinds of categories are impossible to set up the what should be the "main" "keyword" for...

*My favorite part is the category that is hidden (one word in each of the "official and manifest" categories). ;)

4/10 - Two of these I didn't much care for - shell commands & add a B. First is a bit out of most people's ken, I think. Second is nigh impossible to see. But I liked the other two a bunch, and I thought the decoy work was right well played. Keep it up, please!

Properly asasmism 8) :

Neville, yes this was a difficult one, maybe "harder" than hard, but I honestly think the shell commands might show up on OC proper. But I could be wrong. I tried to chose some commonly used ones and especially to include 'Ping' which I thought would be familiar to many and, also, a unique and particular clue as to the group.

The B one, as I've said, is one I like (and seeing you say 'nigh' I am inspired again! :) ) but, yes, that group probably does push the puzzle into Fiendish.

I'll keep trying to find a balance between self-indulgence and fair-play. Thanks for the critique.

And keep yours coming too; I've enjoyed those as well.

The last set were quite obscure!!

@Nikki: Hi. You should remember that the sets only align as you solve them -- so if you refer to a "first" or "last" set you aren't really being specific enough. :)

All these years roll by! impossible to tame
