I've added the multisite function to my wordpress and installed it but when wordpress asked for a site name I wanted to use "blog" but I got a message saying that i couldn't because wordpress use "blog, page, feed etc". For now I've changed it for news.
My main website is in a folder and then my blog (news folder) is a subfolder of that one. So i can access to it like that mainwebsite/news.
What I can do if i want to call my website "blog"?
