New UI for discussions

it's a sphinx template thing... I noticed that because there is a comment after the previous bullet in this list, the html output shows the first two bullets with white space between them, and then no white space between this one and the next. A total hack, but there's so little that we can control in the sphinx template to improve the look of the output that it made me feel better to exert some control over the formatting of this one bulleted list... I'll totally remove it if you think it's an unnecessary distraction.
