Re: signing. A few of the pros have signed this year - Chris was the first to do so, I think, and has signed thankyou each week when he has got through.
Emma B and Michelle then joined in (there’s a few people campaigning on twitter to get more joining), and hen saffron this week too.
Possibly Shirley as well - she may have signed ghost when she came on (but it could have ‘just’ been a bit of armography
)
I think only Chris and Emma B remembered to sign thankyou this week, but it was quite a tense wait, with a lot of them fairly worried about getting through, and they only get a second to say thanks after they’re announced.
Would be nice to see it happen more - my 2 dc who watch have both noticed the pros who have signed so far (their older sister uses Makaton), and they were delighted to see signing being used on ‘normal’ tv, rather than a specific signed broadcast, or something special.
