Can I have more than one domain name "point" to my class creator site?

I already have a domain name that is specific to my graduating year, but when I convert to a multi-year site, I want to register and use an additional domain name that is generic to all years.

The best way to do this is to decide on the "main domain name" for the site and then set up any other domain names to forward to that domain name. So possibly have one that fits the site and then year specific ones point to the main domain name.
