Thanks for the input on the regional spelling stuff. It's not something I'd really thought about before. I'm not personally put off by US English, even though it's not what I use personally.
I think we say "4,000+" and "almost 5,000" which isn't contradictory, but we should tidy that up, and it's a good prompt to do a check for consistency; I appreciate the pickup. This is our number of newsletter subscribers, not customers.
Asking questions is just one of the ways I learn the things I need to. I put the question out here because my Nostr connections are in a broad range of locations (not the only place I asked the question though).
