We create new or update existing web pages all the time. As a rule for us each page is a separate project. If we have sort of a 'hub' page that links out to other pages that are sub-topics of the main page, we might do those in 1 project so the reviewer can link to those sub-pages from the same proof. That's how most of our work works :) Something more along the lines of what it sounds like you're doing is a magazine that we do that has ads from other companies so we need to send out proofs individually to those various reviewers. We have a project that keeps the whole thing running, but each ad is a separate issue under that project and the proof is uploaded to that issue. We've also created custom issue statuses and trained the small team that works on these magazines to update the issue status for the various stages of designing an ad, getting it approved, etc. We then rely on those statuses to indicate when an ad is in progress, design complete, out for review, proof approved, or in revisions. Your thought of tasks to keep them separate would work the same. We went with issues because the various sponsors submitting the ads enter their ad specs into Workfront directly, so we're able keep everything in that same issue.
