I was looking at my Google Webmaster Tools and noticed 152 Crawl errors all related to the my forums and in particular the attachments. From what I can gather here is my issue: 1. To encourage user registration in order to view attachments the member must be a registered user. 2. It seems that since "google" is not a registered user it is unable to "see" the attached images so comes back with a 403 error. Do I have any options here besides opening the forums so that unregistered users can view attachments?
