Wow, thank you both very much! That has been very helpfull.
I decided to use Kort's approach as he used the available tag and I read if thats available it is adviced to use that instead of a php global. But I really appreciate you both posted different approaches.
And, just to show I am not only asking questions I used this plugin to output random newspages (20 items) from the last 3 months, except the current page like this:
But it keeps giving sql errors.
I also tried to add a condition to only list when "$this > 0" but it seems its ignoring anything.
I also tried this plugin: http://www.cotonti.com/extensions/navigation-structure/581 but it seems to no longer work.
I guess/fear the pagelist plugin can not create any output based on comments as comments are just an additional plugin?
