newbie question

[PMGames]

Hi all....I am new here, so I hope my question is in the right place and is not out of line.

Here I go.

I have seen where some sites have been able to do a combine list of topics of the most recent threads posted to from other sites.

like abc.com site has a page that shows a list of the most recently posted threads/topics at 123.com and xyz.com's site...they are all in order of most recent post so they could be mixed up between the two sites, but placed in order of time of the most recent post back.

I hope this make sense. Was wondering who has the hack for this. I would be interested in buying it.

Thanks,

Paul
