On 'connecting' accounts, we don't automatically post, and that won't be a feature we add. As noted in the "Status / Wall" configuration area, Facebook has changed the rules on how you can post to a user's Timeline. As the message states:
Per recent changes in Facebook's Application Policies, automatic wall posts on registration and login are no longer recommended.
To be in full compliance, the user must be aware a post will be made and be aware of the contents of the post beforehand.
If you are properly notifying your users, and still wish to utilize this feature, you will need to add 'publish_stream' to the 'Additional Permissions Request:' in the Facebook API tab.
Facebook also states that posts just for registering on a site should no longer be used as they are 'low value' posts and generally marked as spam. We recommend you don't use the Post on Registration or Post on Wall features, and as stated above, we won't be adding more features like this in the future.
It's likely that the wall post on registration feature will be removed in a future release. You should look into using
Open Graph Actions for Jooma
to automatically post to a user's wall when they interact with your content instead. That's what Facebook recommends.
I hope that helps explain,
