Just went for registration and could not find a way to register to the workshops. I’d like to do all in one, as it’s easier to expense to my company.
Also, could not find where to mark discounted tickets, due to having talks accepted. It goes straight to the payment screen.
I have a different, but related issue. I already registered and paid the full ticket, but I got a talk accepted (technical talk). Is there a way to get reimbursed the difference? Or any other solution? 
Like $505 in free beers at the conference! 
That is tempting but I don’t think my company would approve
@rengolin When you start registration the MLIR workshop add on is on page 1.
You can reach out to LLVM@blineevents.com and they can assist with that.
As mentioned in the notification, the events team will be following up in about a week with speaker registration information and deadlines.
