Hopefully you've made it through the first week, successfully contacted your study group, caught up on any background about the process, and made some initial progress with review!

If you have questions/problems that need a more direct response, feel free to send an email, ask on IRC or create a PR or issue in the github repo as seems appropriate.

One thing mentioned in a Q&A session which hasn't been resolved yet was the possible impact of a bech32 malleability misfeature on taproot upgradeability -- see Pieter Wuill...
