Per your instructions at http://drupal.org/node/207776, it's stated that:
.... the module comes with these panels ..... :
* Guestbook (mini panel - ?=admin/panels/panel-mini/guestbook/edit/general)
This is the comments and comment form for the profile node dressed up to look like a guestbook.
On http://drupal.org/node/214392 (Extra config/helper modules), it's stated:
...... helpful additions ..... :
* Guestbook: ...... For now, a quick and easy way to add the guestbook to advanced profile is to edit the panel page, click add new custom content, and add this code:
<?php
print guestbook_page(arg(1));
?>
Which are you using on this site? Pros/Cons briefly if you don't mind.
I've tried your "easy add" method but can't get GB.mod to show, could you expound on instructions please, i.e. "edit the panel page", how - and "and add this code", where?
Thanks again MC
