I am trying to setup a couple of company websites on a WordPress Network install running on IIS7 and SQL Server 2008.
Ultimately, the sites will work together like this:
Site 1 - All requests for this companies site (regardless of country/region) will go here. This site will just show a map to the customer allowing them to pick the regional site most suited to them (initially North America, Europe and Australia/NZ).
Site 2 - North American site
Site 3 - European site
Site 4 - Australia/NZ site
Sites 2-4 will share the same design and a lot of the same content. Where they will differ is in relation to news, contact information etc.
Ideally, the same user accounts would be able to make changes to all of the sites with the one login and post news to each of the different sites.
My current thinking to achieve this is to install WordPress at sites.domain.com and to then enable the Network feature (using sub-domains). Each regional site will then be region.sites.domain.com. Then, using a domain mapping plugin (recommendations? any IIS specific considerations?) I will redirect the regional domain names to the regional sub-domains I have created.
Does anyone have any recommendations for the best approach to this setup and any tips/tricks to make it better?
