I'M SORRY!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
I know you guys have poured a ton of time into helping me with this.
It turns out I had an ISAPI rewrite rule that was doing
RewriteRule (.*)/forums/(.*) $1/forum/$2 [I]
I don't remember why I ever added this rule in, at some point in the long distant past I must have decided to change the URL and this helped me get them to redirect. I deleted this rule and POOF all the spider friendly URLs began working.
Of course I may have just broken something fairly serious on my site, I have no idea when I put this in or for what. But for now the forums are working with the social networking!!
Thank you all so much for trying, I'm sorry that it ended up being me.
