<p dir="auto">Like TomH said above, this is not a simple "change the data model of changeset comments to add a read/unread state", instead a read/unread state would have to be recorded for everyone who has subscribed to a changeset. -- A less elegant but simpler method would be to generate a user-to-user message to all subscribers every time a changeset comment is created (just like we create emails now). That would give us the read/unread state for free, at the cost of recording duplicates (which users would be free to delete from their inbox).</p>
