You want people who register with Facebook to be given a CBSubs plan? Yes, this is possible using CB Auto Actions. You'll need to create a CB Paid Subscriptions action that acts on the after registration trigger and checks that the fb_userid field isn't empty in a conditional. You can then give them whatever subscription you like.

Ok I have made a CB Auto Action see attached but when I join with facebook it dose not join a plan how do I connect the CB Auto Action to the plan?

That's a Usergroup action. You need to use a "CB Paid Subscriptions 3.x" action. You need to have CBSubs 3.x installed for it to be available.

and can you please delete my [#4008] remository thred its a mistake I think and its waisting peoples time and its been read 1000 times

No, I've already explained what you need to do in my previous replies. Please re-read my replies carefully.

What is "CB Paid Subscriptions 3.x" action.

It's an action type available in the "Type" dropdown. It's used to Subscribe, Unsubscribe, Renew, or Delete subscriptions for the user.

Please see the below tutorial of a usage example of the CB Paid Subscriptions action.
