I am using SharePoint 2007 Enterprise + Publishing portal template + Windows Server 2008. I want to have blog and wiki features as well as publishing portal features. Any ideas how to integrate publishing portal, blog and wiki? For integrate, I mean using the same user name and password to pass through authentication of publishing portal, blog and wiki. And should I setup 3 different site collections for publishing portal, blog and wiki (I find if I setup publishing portal site collection, I can not create blog and wiki sub-site)?
thanks in advance, George
