Thanks a lot.  I think the difficult bit to understand (for me, at least!)

I believe that channel is bridged to IRC (OFTC network), where I'm already
lurking (nick 'henrix').  And I see you have already ping'ed others there.
However, I'm currently on PTO, so my replies there may be asynchronous :-)
