As per my info, Google Scholar is automated, and you cannot index a journal. The journal needs a certain level of professional standing in its field to get indexed.
unfortunately it is not so easy to be indexed by Google Scholar.
Anyway, keep follow my post `cause I`m going to write something about this topic during the next couple of week. There I`ll explain exactly what you have to do, and what you have not to do to be indexed in Google Scholar, ok?
