TPAC registration

Hey folks!

Just a quick reminder that if you're planning to attend TPAC in person, in
might be significantly cheaper to plan ahead:

   - Registration <https://www.w3.org/register/tpac2024> still has Early
   Bird rates up until next Tuesday. That's 360$ instead of 660$ (!!)
   - The conference hotel <https://www.w3.org/2024/09/TPAC/venue.html> has
   special rates which will eventually run out. It's worth your while to book
   in advance, through the booking link at the bottom of that page.

Cheers :)
