How do I make a few domains point to the same place?

I presume I add them to the DNS server then somehow set up some kind of alias on my RaQ?

I've never done this but would be really grateful if someone could guide me through it.

If you mean you have 2 website (domain2.com and domain1.com) then domain2.com want forwarding to domain1.com give metatags at INDEX.HTML:
<META HTTP-EQUIV="refresh" CONTENT="0; url=http://www.domain1.com">

I'm not too sure about the setup on the RAQ3 but if you have a look at Uk2 Raq FAQ (http://www.uk2raq.com) you might find the answer.
You should be able to add the second domain as an alias without too much difficulty, though I don't know if the RAQ3's GUI supports that directly, on the RAQ4 it's very easy to do
