That sounds good too! Dang, I keep getting these emails late! Where 
would I add the above falling code, if I were to take that route? Two 
separate files, or ... and, will that specific code above work right, or 
how would it need modified in order for it to work?

Or, am I just better off installing WP 2.5 on VB.COM, using a modified 
copy of VB.NET's database (with .net links changed to .com throughout 
it, giving VB.COM an exact copy of .NET currently..) Then using this 
domain-mirror plugin, or 301 htaccess redirects like the other Aaron 
said... ?
