How do I export from WP 2.07?

I’m stuck…

I’ve installed WPMU, hoping to be able to start a number of blogs for my mates, and to import my current WP blog into WPMU. However, I can’t for the life of me find the export function in WP 2.07. Am I missing something?

I’ve tried to use the backup plugin which comes with WP, but WPMU can’t import this, as it’s an .sql file.

I’ve searched on Google, here, and on mu.www.remarpro.com but I’m lost, and I’m either being blind or it’s not there.

Help, please!
