EternalGaming and Xaraya

Hi there Fellow Xaraya Users, how are you?

My sire Eternal Gaming (http://www.eternalgaming.com) is using Xaraya, we
have been trying for the last 6 months to make our own Content Managment
System, but that takes alot of time, as you all well know, Well we found
Xaraya, 

We thank god we did, but there are some things I was wondering.

1. We have a complex Cats system running as you can see. 

We need to be able to view all artical types with one cat tree.. as it is
I don't think we can, is there a way we can do this?

2. We have about 10 sites, and we want them all to share a user DB and
nothing else, is there a way to do this?

I want to thank the Dev team for all there hard work, this is already the
best CMS out there and its in beta still.

Thank you
Robert Town Jr.
