How do I get TextMate to default to Textile format?

I love using TextMate for blogging, but at some point since the first version it stopped defaulting to Textile format, instead defaulting to plain HTML, so what I end up doing is posting, then changing the Format header that it inserts on posting, then post again. Annoying.

Whether it was upgrading my server software or Textmate that caused it to change, I don’t know.

Any clues?

UDATE: Mike Greiner sent me a hint: Open up File > New From Template > Edit Templates in the menu in TextMate, and edit the Blog Post (Textile) template to include the Format: textile header. Actually, that’s not 100% what he suggested, but that’s what I did, and it works. Thanks!
