I thought of a nice domain name with specific keywords for an existing site.

Should I use a forwarder to forward users from this new domain name to my existing site, or should I change the domain name of my existing site.

Since my site is only two months old and I don't mind the setback with regard to SERP's, I am thinking I should just change the name of my site.

What say ye?

Instead of wasting the hard work I have invested with link building and directory submissions ($299 for a Yahoo! directory submission), I am going to copy and tweak my existing site, associate it with the new domain name and run both sites concurrently.

yeah, that's what i'd do too, how long does the listing last in yahoo directory? maybe when it expires, and you have to renew, you could change everything over and sell the original domain name?
