New/improved domain name - Should I forward? How?

I own a reasonably active forum at

PHP Code:

www.mu-43.com 


We have lots of pages indexed in Google, and I think vbSEO has been extremely helpful in this regard.

Recently, I was able to pick up the domain

PHP Code:

www.mu43.com (sans hyphen) 


I currently have the new domain forwarded (by the registrar) to the old one.

Should I:

• Leave it as is and announce to the members that they can use either URL
• Change the site to the new domain and use htaccess to forward all the old to the new
• Something else

I'd appreciate advice from some of the SEO experts here. Thanks in advance!

Moving is usually never a good idea, especially if you're well-indexed. I would keep it as you currently have it set up.

Thanks, Brian.
