Adding a bullet point on wordpress’ “recent comments”

I’m trying to add a bullet point in front of each “recent comment” on my site. The site is gurconnect.com I’ve been searching up and down and can’t figure out a way to do this that works. I’ve played around with different plugins as well. I don’t even necessarily need bullet points per se, I just need the comments to be able to be distinguished from each other in a way that makes it more readable. I’m about to gouge my eyes out Any help?
