I also need to know this – I am trying to link to a friend’s Flickr page, and the link contains an “at” sign – @ – which wordpress is filtering out. I went into the database and fixed the link in wp_links, but still something on the display is filtering out the character. I’m very comfortable editing php and regular expressions – I just need to know which darn file to go after! I’ve hunted and searched and can’t find it.
