Since someone asked if Footbridge will import Radio posts to Movable Type (it won't, it'll only mirror new Radio items to Movable Type), I discovered the version of Bill Kearney's Exporter I used (0.2) to move my Radio posts to Movable Type--after fixing the broken BODY: thing and ignorance of Radio's own titles, anyway--wasn't the newest version of Exporter. So I hope 0.4 supports those things rather than folks having to hack them in.
