[pmwiki-users] Changing the default wiki group?

[Felix E. Klee]

Currently, users loading

  http://www.dom.ain

with their web browser get the contents of the page

  http://www.dom.ain/Main/HomePage

displayed.  Now, I want to change the default page to

  http://www.dom.ain/Portal/HomePage

How can this be achieved?

Note that Main/HomePage should not be altered as the wiki group Main
will still be used.
