The key that I'm getting is different than the one on github.
I'm not sure why support is being scattered across so many different social media systems, rather than just one, it seems counter-intuitive to fragment the information. Sigh.
I see that Chat via the Thunderbird email is one alternative - at least I don't have to add yet another app. (I had no idea Thunderbird even had a Chat feature.)
I'll give it a try. I'd rather ask first than plow ahead, make a mess, then have to undo the mess and start over.
Thanks.
