Multiple Shields on the Uno and Duemilanove

I'm new to the Arduino community and the equipment and i was wondering if anybody could tell me if it was at all possible to use two shields on one Arduino at the same time?

It is. Most shields use only a few pins. You need to find out which pins each shield uses. If they use the same pins you then have to find out if they can be shared.

There is the Shieldlist website

Thanks alot, i will definetly be using forum a lot in the near future :)
