Blogs were created on Jul 8 2017 and you need to be registered and have at least 1,000 points. The first blog was Rat Direction by GemHeart.
I think Advice Columns were created around Mar 30 2016. You need to be registered and have at least 25,000 points. The old requirement was 10,000 points. I think the first Advice Column is Cindy’s column by Cindy7872 AJ.
