This is the shortlist: every ad line that survived the first review round. Enter your name, then approve or reject each line, move it to a different persona if it belongs elsewhere, and leave a note where it helps. Every click saves immediately under your name, so nothing is lost on reload and your decisions never overwrite anyone else's.
When you have been through every section, press Finish review. That records that your review is complete so Seth is told to gather it. You can still change decisions afterwards; press it again to update.
Every line you approved, grouped by the persona you approved it under.
