No - 6.5 you can edit all the forums in one handy little chart. That's one of the main reasons to upgrade.
Control Panel-> Group Management -> Group Accees (tab) Check your groups at the top - and then you'll see a chart where you can overview everyone's access. (Example, check the guest button at the top and make sure they are all set to no access).
I am still "finding" things in 6.5 I didn't know I could do. I did not realize I could actually edit the online.php file from within the language editor. I was all set today to try and write a mod to add it to the admin menu when I found it. lol
