I absolutely love DoInk! It's a great way to get your art out there and find friends in a safe, online community. The art and conversations are monitored but if a specific person has a problem or thinks a video is "inappropriate" they can tell the admins. Generally everyone is very supportive of each other. There is a way to get virtual coins to buy props and extra design tools that cost actual money but you can use paypal. I've used it several times and never once had a problem. I personally have never had any problems with other people on the site but I have seen one person talk "sexual" to another, but like I said earlier you can always report them to the admins. I know several schools have used DoInk and reccomended it to their students. Overall it's a fun site and I would reccomend giving it a try:)
