do you need two different looking blogs? or you want the same content on two domain names?
if you want the same content and two domain names, then you can get an url alias, as far as i know.
did you ask your hosting provider?
see this example:
http://sligoarts.com/
http://sligoarts.ie/
NB: i’m probably going to change it at some point to a pointer, so lessen confusion.
only if they’re using Apache, you would need to ask your host to use ServerAlias in similar manner:
<virtualhost ….>
Server domain.tld
ServerAlias *.domain.tld domain.tld
ServerAlias *.domain2.tld domain2.tld
</virtualhost>
I can do the htaccess side of things- but all of the links in the temlates are http://www.domain.com/wordpress/whatever so all the links on domain2.com will point to domain.com and not domain2.com (i don’t want the two blogs to acknowlage each other)
It doesn’t seem to be a simple thing. See this thread with a very similar content:
