Yes, all you have to have them do is put /join at the end of their linking code and it will work. Just confirm with the program owner first if this is something they would like you doing as some of them frown upon it. This will also be a disableable feature in version 2.0 for program owners who don't wish to allow it.
We have no problem with people giving NATS advice, just please be careful before you do
Thanks guys!
