Yes, you can't post links. You have to put a space in the link after the ".", or use a comma instead of the ".", or change the link anyway else to not make youtube think it's a link.I tied to post 3 comments today on Youtube, each of them had a link in it, and Youtube kept showing "Error, try again".........When I removed the link from the comments, they went through. So youtube does not allow people to post LINKS in the comments?
