I've been asked to share how you remove the dotted lines from your blog.
Go to Customize
The go to Edit HTML
In the box of jumbled letters and words, scroll until you see the word "dotted" and delete it! I think it's on there three times? I could be wrong.
An easier way is when you get there, click Ctrl+F and it'll pop up a box, asking for the word that you want it to search. Type in "dotted" and it'll bring up one for you, one at a time, highlighted too. You deleted it and click "Find Next" until all the "dotted" words are gone.
Then click PREVIEW to make sure that you did it right and didn't screw up anything! Please don't make the mistake of saving it without previewing it and and having it ruin your blog!
