You'll find the new option in the Manage Skins page as well as when you upload a new skin.
There are a number of special tags you can use as well, which are displayed next to the edit box.
Here they are for quick reference:
[list] and [/list] to start and end a list
[*] and [/*] for each list item.
[b] and [/b] to Bold text.
[title] and [/title] for a title/heading
I've made some variations on these that will also work.
I.e. Here is the complete list:
[list] or [ul]
[*] or [li]
[title] or [h]
[b] or [bold]
Up to you which you use, you can start with [b] and end with [bold] for example and it'll be the same thing.
Just make sure you end all your tags
