Knight,

The primary way of obtaining the credentials of the currently logged in
user is through the AUTHENTICATED_USER attribute of the REQUEST object,
ala:

<dtml-unless "REQUEST.AUTHENTICATED_USER.getName() == 'Anonymous'>
   Important stuff
</dtml-unless>
   Unimportant stuff.

You probably don't want to hardcode too much of this stuff into DTML,
this is what permissions assigned to objects and roles assigned to users
are for.  Read the content manager's guide for more information on
permissions and roles.

The subject is a big one.  I'e never used MySQLuserfolder, so I can't
give you much info on that in particular.  I assume it operates much
like the "basic" user folder that comes 'preinstalled' in the Zope root
folder, in which case you'll need to read up on AUTHENTICATED_USER. 
Searching the Zope.org site for "AUTHENTICATED" should turn up a bunch
of hits (although AUTHENTICATED_USER will probably not because of
limitations in our cataloging engine).  The How-tos that you'll find
through this search are probably good for this sort of thing as well.
