First, publicly naming sources is not allowed in the forums. Second, you need to get your post count up in order to get private messaging enabled for yourself. No one is going to post "where you can get this", "where you can get that" right out in the open, especially to someone whose first post is requesting sources. It's nothing personal. It's just how it is. Go post some comments in other people's threads. Not sure how many posts it takes before DM messaging will get enabled for you, along with a search function, which can be quite useful. But, you need to post more, and you can even start your own thread and tell people more about your situation. In other words, become a part of the community a bit first. Does that sound reasonable to you?
Oh, BTW, welcome to SS.
