They hired Lincoln Quirk for the UK board in June:

(I'm a trustee on the EV US board.)

Thanks for checking in. As Linch pointed out, we added Lincoln Quirk to the EV UK board in July (though he didn’t come through the open call). We also have several other candidates at various points in the recruitment pipeline, but we’ve put this a bit on the backburner both because we wanted to resolve some strategic questions before adding people to the board and also because we've been lower capacity than we thought.

Having said that, we were grateful for all the applications and nominations which we received in that initial post, and we're still intending to add additional board members in the coming months.
