I note when a match is tagged in one profile of a tree, it is also tagged in other profiles. Will a profile acquire tags from archived profiles? If not, what is the best process to maximize tag sharing?
Yes, a match isn’t archived unless all profiles it appears in have been archived. So if you have 2 profiles: one that has been archived, and one that has not been archived, and the profiles share 5000 matches, those 5000 shared matches are not archived because they are still associated with the unarchived profile.
