1) attachments are stored in the database. Even if I knew how to save the whole forum as .mht files (and I don't), it would probably increase the size of the db to do it that way
2) Post counts: I have no idea what's wrong with them, and frankly, there is a reason why they don't show up in people's profiles anymore. We had a lot of senseless, post-count-raising garbage back when we had them shown. If anything, I'm tempted to make them not shown in profiles, as well.
