I know you wanted to fast-track some of these tasks so you could get unblocked. Which of these are most important to do now (this sprint) and which can we save for next sprint (kicking off next Tuesday)? I don't wanna cause chaos by introducing new unestimated tasks into a current iteration, but if there's stuff that needs to get done asap, I'm okay with bending the rules – as long as our glorious scrummaster is okay with it, too ;)
