Their source differs from the original. Ironically, they translated an already-translated article.
I think this is fine, but the problem is that we're just seeing users post articles and then link them to count as substantial posts. I don't like that.
This will not count as substantial posts for OP because it is just an article being copied and paste.
Anyway, I think OP just wanted to share this especially to the new comers here. However, I do not really know the statistics nowadays of the number of newbie registered in the forum per day. I think it is already low in numbers of new registered bct accounts.
Somehow OP's post is informative but I guess it is better to get things simplified through a list form and then for more info the link or site of the blog must be provided in that post.
