Hi again, dml! This is true and the way you'd generally use, but after it's been there awhile, that option's not available. What to do? No worries, PC's thought of that. From the FAQ page:

"You can edit your post or delete it for up to 4 hours after posting your entry. After that time, please contact a moderator (by reporting your own post) to have it edited or deleted. Why do we limit your time to edit or delete a post? We have found that, in the past, some people were using this feature to "change history," which resulted in confusion and member upset."

Hope that helps.
