1: Click design on the top right corner
2: Click on either the left or right section depending on where your layout is and click add a gadget
3: From the list that pops up choose link list
4: Enter the URL of the website you want where it says new site URL and then underneath add the name of the site
5: Click add and then repeat for any other sites you want, when finished click save and voila all done!
If this doesn't make sense then I'd stick with CeCe's suggestion and wait for Eva lol
