I would definitely enjoy some collaborative crossword solving over Discord. I'm moderately good at British cryptics and moderately bad at American-style straights where the grid has hardly any blanks, so maybe we have complimentary strengths? Between timezones and Shabbat it may be hard to find a compatible 15 minutes, but... maybe just after you finish work, which is last thing in the evening for me.

Sympathy on the random back unhappiness, I'm glad it's better now.
