If you have nested numeric lists, ProjectForum follows the default HTML approach of numbering them with decimal numbers, for each level of the list. But, you can change this if you'd like, so that nested levels are 'numbered' using a different scheme.
For example, insert the following bit of CSS into the main stylesheet of a custom theme:
div > ol { list-style-type: decimal; }
div > ol > li > ol { list-style-type: lower-alpha; }
div > ol > li > ol > li > ol { list-style-type: lower-roman; }
The first level will still appear as "1, 2, 3...", but the second level will now be "a, b, c", and the third level will use "i, ii, iii...".
This tip courtesy of Pancho Castano.

Note that "lower-roman" should have a dash between the two words.
Other counter styles available are "upper-alpha", "upper-roman", and "decimal-leading-zero".
