How to Align Objects (2.5)

Hey guys, is there any way to align two objects so that their center point is in the exact same place? Example, a sword and it’s handle have the exact same center axis? When I build in Second Life you can “snap” objects into position together so they are touching perfectly and not overlapping, is there anything like that in Blender 2.5?

Thanks!

On the 3dview header there is a magnet icon and next to it various snap potions. You can also use the Shift+S snap options to precisely place objects.

Thanks, awesome! I got it, and have a simple object. Do you have any idea how to import it into Second Life, or is that a topic that may need its own thread?
