OK, I made the mistake of signing up with TypePad and right now it's too much of a hassle to move my blog to another service. For now though, the least I can do is to warn you about the poor reliability TypePad offers.
If you haven't started a blog yet but are considering doing so, do it somewhere other than on TypePad. At this point, I'd be willing to pay twice the annual fee I pay TypePad if it would mean I could count on more reliable uptime.
The service is terrible and the features are very limited. Do yourself a favor and look elsewhere for your blog hosting solution. Trust me on this!
