New Site Add Form Question

["Bill Wilson" <wtwilson3@earthlink.net>]

I'm looking over the scripts and getting ready to install Ringlink.  On 
the new site add form, I haven't been able to figure out this line:
<input type="hidden" name="pw" value="" />
Why do is this line needed?  Just curious.

This is the true joy in life:
- Being used for a purpose recognized by yourself as a mighty one,
- Being thoroughly worn out before you are thrown on the scrap heap,
- And being a -force- of nature instead of a feverish, selfish little clod of 
ailments and grievances - complaining that the wo
rld will not devote itself to making you happy.
