On the bullet point issue, inserting bullet points gives code like thus, with no bullets inserted -
<ul>
<li>First</li>
<li>Second</li>
<li>Third</li>
</ul>
As to why it doesn't respect the "no filter" text filter for super users, I can't say yet, but this will fix your immediate problem -
Change the first line of code in the HTML editor to this -
<ul style="list-style: disc outside;">
- changing "disc outside" to whatever bullet type you want.
Inserting the css into a single tag restricts it to just that module.
