Nofollow on all external links?

[Walalayo]

Hi,

Has anybody come across a way of applying rel=nofollow tags to all external links?

I'm taking part in an SEO contest (hopefully people will still help now I've said that  ...) so obviously don't really want the negative effects of having quite a few outbound links.

I'm using a wordpress blog, and can't find any plugins of this nature.

Any help would be really appreciated - Thanks in advance!

Perhaps - if you add your own site to the whitelist then all external links should become nofollowed. But I haven't tested that.
