Lists are a good way to present information such as links, so that's what we're going to do here.

Beneath your "Links" header, create an Unordered List, and make each link that you have there into a List Item, with a single blank line in between each entry (hint: it's not that hard, just think line breaks). Add some more links. They don't have to go anywhere, just put them there to pad out the list. Now, create a sub-list underneath one of your List Items, and make it an Ordered List, starting couting at 1, in Roman Numerals, and have a few entrys, it doesn't really matter what.

Once you've got this idea of lists, then they're all easy, because they're all the same in their basic format.
