To include a direct link:
When you are on the website you want to link, highlight the address line, click control & C (to copy it) & then when doing your QB post do control P (to paste it into your message).
Or, if you include the http:// in the address you include in your post, it will be a direct link.
http://www.home.howstuffworks.com
I'm not seeing the info you posted about, so maybe you need to get to the page it is on to get the correct address for a link.
