Gregory's Server@kbm0 I’ve been programming for almost 40 years. Used BBSes then IRC. Every BBS was proprietary. Been using git circa 2008 and GitHub circa 2011. Still waiting for that EEE. And one can always move their repo easily - even from a clone if needs be.
No disagreement about non-email forms of comms, though. I only signed up for Discord for a particular game long ago. And while I hate changelogs being put there, if I *have* to contribute using it, I’ll do what the maintainers prefer.
@heaths As an aside, in my day job on closed-source software we use M$ Teams a lot for discussion. I often find myself looking for something that was mentioned 18 months ago but the search facilities are limited, and I've not yet found a way to export an entire conversation so I can just grep it. This was always so much easier with email, and illustrates the difficulties with using proprietary platforms for collaboration.
