Hope you can help.

Hello:

I am using Forum_03.20.01 and DNN 3.2.2

Things were going fine with new users when created. Only those migrated users are facing this problem. For example, admin and host users can access this very easy.

How does the forum work? I mean, what happens when the user first logs in, is this updating anything in the forums tables? if yes, let me know what is it, so that I can do this magnually for all the migrated users. I beleive new users would work just fine.

How can I make a forum editable, which is, to make registered users only post in it?

Thanks
