Random Sort

I maintain a Web directory of fundraising software hosted on IIS
(www.tfraise.com/listings.aspx) and cannot figure how to get my listings to
be rendered unsorted or, more to the point, sorted in a random manner each
time the page is requested. I do not want to give vendors/software with
names starting with the latter A a constant top ranking because of
alphabetical sorting, but give every vendor/software an equal chance at
first user request. Is this really complicated to do? I had a hard time
getting it to work as well as it is now.
