PopTop

Is it possible to set up a new account on the wiki, or does that require an administrator? I wanted to mark the page http://wiki.freeradius.org/PopTop as obsolete and applying only to the 1.x versions of freeradius. These are the instructions I was originally folowing, and they distinctly do not work with 2.1.8. If anybody has a working 2.1.8 setup for PopTop I would greatly appreciate your advice.
