There's a group dedicated to...nastiness and they allow it to remain.
When I had trouble initially, nothing was done. See, they have 3, 000, 000 users and can't do much about bullying etc. I have heard similar complaints by other people.
Someone said something...horrible about my newborn daughter so I decided anyplace that permits vile people like that isn't the place for me.
A friend of mine is having even scarier problems.
Rav is great for patterns but...stay away from any but the main boards.
