@Ryan: Thanks for providing the tutorials section - and the pager for monster-threads like this.

@druru: Thanks for your PP WPS tutorial. Will use that later to tune my setup... Btw.: WPS should be Website Payments Standard as they call it over at PP . I agree that all documentation related to a topic should be concentrated in its child (handbook) pages, like on drupal.org. Will post my doc asap (within a few days).
