Edit option for posts made by others in forum

Well, I had such great results in getting my post Drupal 5.8 upgrade issues resolved, I thought I'd ask about another that's been puzzling me for a while. First off, I should say I have both ACL and Forum Access modules installed within my Drupal setup so as to create private discussion areas. However, I noticed that the EDIT option is available to others for posts they have not made. In setting up permissions for the forum itself, I was very careful to allow those in authenticated roles to create topics and edit their own posts. Within the FastToggle Module and the modr8 Module, I was careful to give 'moderator' permissions only to the role I have setup for that. So, why is that EDIT option showing up for those in roles where it shouldn't be? Any ideas? Thanks in advance for any suggestion. So far, it hasn't been an issue in these past few days as those posting messages have all been in private areas. Concern is when people will post in the public areas, where - of course - it seems people do darn near ANYTHING! ;-)
