[Zope] Squishdot problem with suggest_author

[Kyroraz]

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
