Re: Tikipedia changes
One thing to be aware of is that the heading tags in wikitext have been remapped in Tiki 2 because h1 is reserved for the page title, so the ! syntax produces an h2 heading, !! produces h3, and so on. Sorry if this wasn't documented anywhere.
If you look at the page with Firefox and the Firebug add-on, you can see what CSS selectors are being used and what their properties are.
