Managing Permissions for the Blog Feature
When configuring this feature, you can specify which roles can do each of the following:
Post blog items
Administer the feature instance
Comment on blog items
You can grant the first two permissions from the Access screen. You can also control commenting permissions using the Setup menu.
Note that there are no global feature operations for the Blog feature. What this means is that any user with permission to display a page hosting the feature instance can display the instance and any Blog posts that have not been restricted by authors.
By default, no roles are allowed to comment on blog posts. What this means is that if the author of a post enables commenting, the Discuss link will be active on the post, but users who click through will not be able to add comments. To resolve this, you can configure the feature instance to specify that some or all roles can comment.
Log in to the portal as a member of the Administrators role or as someone with Can Admin privileges for the appropriate context. Navigate to the Blog feature instance and maximize it.
Click the Setup link.
The system displays the Setup screen.
In the Contents Permissions section, select the roles that should be allowed to comment.
Click Save.
