@greenpartyni I'd say “welcome to Mastodon” but I see you've already met the welcoming committee!
I wish @plaidcymru would do this - they do have a profile here, but that dates back to November 2022 (when the Welsh Mastodon server was briefly in the media's eye here) and they haven't posted since a fortnight after they joined. Not even cross-posting from other platforms, which would cost them nothing, presumably.
But then @ZackPolanski is no better - and yes, I know he's not your leader!
