 Hi KS Comment 2 of 2 |

Dear KS,

Thank you very much for devoting so much of your time to providing problems for this group. I really appreciate it.

If you are interested in joining another interactive puzzle group, based in  India, please send me an email.(I think you know how to find me.)

There are many "number-crunchers" (not me!) in this group who would respond positively to your challenging puzzles.

Best wishes,

Josie

PS. To anyone else who is reading this message. You, too, are welcome to join this group.
