Right, unless I'm mistaken - these are the counties already set up on #BlueSkyCricket:
@durhamcricket
@essexcricket
@glamcricket
@gloscricket
@hampshirecricket
@kentcricket.co.uk
@lancscricket
@somersetccc
@kiaoval.com
@warwickshireccc 
(add .bsky.social to each)

Middlesex will be last, won't they!
