Stacks

I am just getting used to Leopard on my Mac, and i'm starting to like it, even though it's much different compared to Tiger. I have a question about the stacks. I know that they are set for certain folders like documents and downloads, so i got rid of them for those 2 folders. Would there be a way to create a new set of stacks for my minimized applications? Also, could i create a new stack for my school folder?

Yes. Create the folder wherever you want on your drive. Name it as desired. Drag aliases of the Apps you want in there, then drag the whole folder to the Dock. It will turn into a stack.

For your school folder you can put the actual files in the folder and then drag it to the dock.
