I am curious why I can't add in Tri-Art Acrylics under the acrylic paint page? It's a legitimate company, a product manufactured in Canada, with over 5 different lines of paint distributed all over the world. I've tried to add this and it's removed cited spam, but it's not. If there is a way of going about including this information on the wiki, please kindly direct me, with thanks.
