1 I need to know what the grid is, how it works and who's using it to understand if it can help me
2 What is a grid middleware? What makes EMI special? Who's using EMI? Can I see real use cases?
3 What do I need to use EMI? What can I read to learn the beginnings? Who can I talk to?

4 I used ARC/gLite/UNICORE/dCache. What will change once my institution switches to EMI?
5 Where can I find in-depth documentation? What if I'm in trouble?
