Our wiki software is ugly

[Scott Ritchie]

Our wiki software needs a major update, especially as we start to expect
users to actually read it.

For instance, look at the FAQ page: 

Then, click on edit and see how it should look.  From what I can tell,
there are a few obvious errors:

1) The wiki software is completely ignoring line breaks.  I could hit
return 4 times and the HTML rendered would be on subsequent lines,
without a break or paragraph tag between them.
2) For some completely strange reason, if you make a list item that
includes a link then the entire list item will be in a smaller font.
This makes for extremely weird and inconsistent lists when a link to
another wiki page is included in some, but not all, of the items.
3) Header text is almost impossible to figure out right, and there is
absolutely no standard of what we should do.

Is there a reason we chose the software we did?  Would it be too hard to
migrate to something else, or at least fix the display bugs?

Thanks,
