Hi! It looks to me when I go to your profile page that you are a member of several communities including this one! If you post on a new community, you will automatically join. Let us know if you need more help or I am not fully understanding your question. Thanks and good luck!
If you send an Friend Invitation, and the recipient Accepts you will see the comments, journals, notes etc that are being made to their feed. So please , feel free to Send an Invitation to anyone's whose work here you wish to follow. Thanks for planning on helping out there. God Bless you.
This feature has been removed. It is up to you to go to each friends page and see if they have posted anything. I really do not know what the advantages of friending someone would be. But perhaps the friend feature is the next feature to be removed.
