At least daily, I check the various Slack environments in which I participate. (Actually, since that rose to about eight, it's no longer strictly true).
The best way to contact me is by email, at the address provided above. I ordinarily check email every day.
I can be reached on Signal using my public phone number, and on WhatsApp and Telegram using private numbers.
I have several phone numbers. I try to avoid actually using phones as much as possible, though. Currently none of them is public, though I plan to return to using +447779296469; that number is however unreachable today.
My inbox receives vast amounts of email, sometimes unmanageably so. Here's a chart of its size against time.
