No, I think what happened was I was trying to rever a mistaken edit and the system automatically added them. I didn't notice them at the time. When I am manually adding them, I do not add the slash either.
Thanks for the advise and feedback. I have been trying to figure this out mostly through looking at other pages and doing a copy and paste. If there are any specific pages that are correctly formatted that I can use as a guide to adding information, I would gladly look at them and try to improve the style that I use.
I see your point. I didn't know about the source editor (what I am assuming you are talking about) and had just been editting in the info-box window, which is probably what led to the same line thing you are talking about. In the future I will try to make it a point to use the source code now that I know what is does and how to work with it.
Click the arrow at the right of your avatar, and go to "My Preferences"
On that page, go to the tab "Editing", there you can set the preferred editor
When you set it to "Source editor", all your future edits open in the source editor when you click the edit button ;)
