# TODO: Every post in a PRIVATE MESSAGE looks the same: each is a UserAction::NEW_PRIVATE_MESSAGE.
# So we need to remove all those user actions and re-log all the posts.
# Post counting depends on the correct UserActions (NEW_TOPIC, REPLY), so once a private topic
# becomes a public topic, post counts are wrong. The reverse is not so bad because
# we don't count NEW_PRIVATE_MESSAGE in any public stats.
# TBD: why do so many specs fail with this change?
