Instead of doing li tags, you could just attach bullet points as Unicode characters to the text of your messages. That'd get the same visuals but avoid anything weird with HTML indentation. (also, do you have an answer to my webdav question or were you just liking the post? I'm not sure how to parse liking-without-commenting on question posts.)
You might be able to do something like p::before, but just putting your "bullet points" into the text of your HTML proper should definitely work, and it's not like anybody's going to not have Unicode support. (and if you're really worried about it, you can locally load the font.)
That reminds me that I have to upload some code there! Hope they're back online soon
ok i defragged my computer and it's working fine now
