Like many people, I'm new to multisite and trying to get my head around the whole thing. Hoping you can shed some light on whether it is what I need to achieve the following.
I have two domains that will use the same posts/content/everything: 'mainsite' and 'secondarysite'.
All I need 'secondarysite' to do is load 'mainsite' but display a different header.php - at the very least, a different logo - and possibly a different index.php (but this is not essential).
Preferably the end user will only see 'secondarysite' in the URL bar, with little or no reference to 'mainsite' throughout their browsing. Vice versa for visitors to 'mainsite'.
Is this something which multisite could be used for? Or can you recommend a better way?
