When writing a new post, right above the box for inserting trackback URIs it says:
Separate multiple URIs with spaces.
But when I look at the help page (http://wordpress.org/docs/reference/post/#trackback), it says:
Trackback an URL
This sends trackback pings to the URLs you specify in this field. You can trackback multiple URLs by separating them with commas. Whitespace between things is insignificant. For more information about Trackbacks see Trackback explained. (Which doesn't exist yet.)
I got to the above link from the bookmarklet help link. Is the information in the above link outdated? Which is the correct way to insert multiple trackback URIs?
