Hello,
I have two queries:

How to acquire a CodoForum license? I've seen it somewhere on the site but now I can't find it.
On my site only registered users can create post and reply. Now I want to make a category where anyone, even if not registered, can create a post and reply. In that case, I create a category and assign permissions to all users to create new topics, in particular to the guest user.When an unregistered user ( guest ) enters the category, the "New Topic" button appears correctly. Enter to create the post, but when you click the Post button an error occurs.

Any comments or bux fixes?
