This basically explains that compacting is an operation that should fundamentally be transparent to the user, and that Thunderbird makes the user aware of it for ... no good reason. Thunderbird will compact things for you as needed even if you don't explicitly ask for it, so you don't need to worry about it. Evolution doesn't bother the user with this, which is the better option. Stefan
