How do you add a domain pointer on raq4? www.site1.com and www.site2.com go to the same location?

1. Setup DNS for both domains ie. A records and MX if required
2. Under site management add the pointer as an alias eg. www.domin2.com, domain2.com (you should already have the main domain aliases setup)
3. Save settings..
That should work - did I forget anything?
