[Zope] Squishdot problem with suggest_author

Hmm, I can't seem to get my squishdot site to allow postings. Everytime a non-logged in user tries to post a suggestion for a topic or a reply to a existing post, I get: Zope Error Zope has encountered an error while publishing this resource. Error Type: Unauthorized Error Value: You are not allowed to access suggest_author in this context The odd thing is if I press BACK on my browser, and then FORWARD, I get in. Any ideas? The site is http://www.battledroid.org Jason
