This is a link to an index page by a Princeton systematic theology PhD candidate, David Congdon, providing further links to articles on the internet (roughly 2005 through early 2007) on universalism. Gregory and I have participated in a few of them ourselves. 
His index page could be updated somewhat I think. 
But it’s still useful.
David’s “dogmatic sketch” for why he’s a universalist can be found here at this link.
