Here's how you do it:
First, click on the Edit Html tab as you're working on your post.
Put <s> in front of the text that you want the line to go through.
Put </s> behind it. The backslash is very important.
For example, this is what the above sentence looks like when I click on the Edit Html tab:
I've got to get the kids to sleep so that I can <s>blog</s>Have fun with this one!
