Just trying the multisite feature for the first time. The primary hostname is blog.domain1.com. When trying to create multiple sites, it only allows me to create XXXXX.blog.domain1.com. But what I really want is blog.domain2.com, blog.domain3.com, etc. All on the same Apache instance, same database, same IP.
Is that doable directly with WP? I could try some Apache rewrite wizardry, but it just seems ugly. Any suggestions?
