Hi. I'm currently trying to achieve the following:
1-Have a self-hosted WordPress site with a customized theme.
2-Have it working with the same theme and contents, but in two languages (English and Spanish).
3-Have the user redirected to the appropriate language according to his/hers browser settings. They should however be able to switch from one language to the other.
So far, I've been able to enable multisite network on WP based on the instructions posted here: http://codex.wordpress.org/Create_A_Network, and here: http://www.netmagazine.com/tutorials/build-multilingual-site-wordpress.
*It was not a completely fresh install, since I already had a theme and child-theme installed but with no content except for custom CSS and menu.
I also installed the Multisite Language Switcher plugin but I have no idea where to go from here.
