Assuming you need to do this in the listinfo.html template and not in
the Mailman/Cgi/subscribe.py module that processes the form, You would
need to create a template that uses scripting (javascript) to require
that the real name entry be non-empty or pass other tests before
posting the form.

The difficulty with this is you cannot install or edit such a template
through the list admin "Edit the public HTML pages and text files"
function because the protections against XSS attacks won't allow
templates with scripting to be installed this way. Thus, you'd have to
install the template per the FAQ at <http://wiki.list.org/x/jYA9>.
