I would like to run a multi-site installation of WordPress for people who go out with an NGO I support. As some of them go alone and others go together or with a family, I have registered two domain names to cover both options. I would like the individual blog addresses to be name.goeswitnus.nl and name.gowithus.nl (slightly different URL’s as they are Dutch, but as an example).
How can I use two domains for one installation without it automatically reverting from one to the other? (like domain pointers that always resolve towards the original domain)
