I am planning a setup for a network of wordpress blog sites and I need some setup advice. It will consist of 3 - 5 domains, all using the same theme.
Each domain is also going to have it's own forum. I would like to use PHPBB3, but this is not set in stone.
I would love to have single sign on across all 3 wordpress domains and forums. If Single Sign On is too difficult, or not possible, I do want to have user accouns synced between all three wordpress installs and forums.
I welcome any advice or plugin recommendations for this wordpress network.
