I think you got it, mostly. :smile:

Functional, concise, and readable. Good job! :+1:

You only have some minor HTML structure/syntax issues:

  • the direct child elements of lists (either ol or ul) should all be list items (li).
  • I don't think "<list>" is a real HTML tag.

It doesn't look like you really need lists here, just a bit of indentation. You could use <blockquote> tags or a bit of CSS styling to get the effect you want.

Thank you!

Haha, you're totally right, <list> is definitely not an HTML tag, but [list] is a BBCode one and I think I accidentally mixed the two.
