> I'm not sure why it was like this, but I agree that we should not capitalise. Maybe Tim could comment about his view before we can finally commit this, as I want to hear his concerns.

Yep, I agree fully. I was just hanging back to give Jason a chance to
comment, in case we were missing something. Perhaps give it another
few days in case he's up to his eyes in other stuff. Otherwise assume
he's got nothing to say.

Cheers.

Tim.
