Hi James,
Sorry about not getting back to you, email really is best for me. I try to check out the admin forums each week but I can't be everywhere
In response to your gripe with vbseo, I've seen it run fine on sites will millions of post, I find it hard to believe they are unwilling to work with you.
Did you submit a support ticket?
I wouldn't take the option of changing your url's if possible, if you want to chat with me personally, my email is brandon.sheley[at]gmail[dot]com otherwise I'll try to contact Juan and alert him to this thread.
