WordPress Has A Slight Evil Tendency

When importing entries from MovableType into WordPress, it doesn’t enable trackback pings on the imported entries.  Now I have about 300 old posts that don’t have trackback enabled.  Anyone know how to enable pings enmass?

Oh and yeah, that’s about the most evil thing I’ve found about WordPress so far, overall I’m very impressed but I’d hate to ruin my evil theme for the evening now…
