Posting to the CentOS Blog
The CentOS Blog is one of the places that serves as the official voice of the project. Any member of the CentOS community is welcome to post articles there, upon approval of the Promo SIG membership.
blog.centos.org authenticates against your CentOS developer account. That is, your https://accounts.centos.org credentials.
Once you have a CentOS account, activate your blog.centos.org account by logging in to the blog.
Finally, email the CentOS Promo mailing list, telling us your blog username, and requesting author permissions on the blog. If your request is approved, we'll let you know when you have sufficient access to post to the blog.
If you want someone to look over your post before publishing it, we are glad to provide that service too.
