For anyone who uses Scrivener, you can use it to plan and track blog posts. Just create a project called “Blog” or whatever you like. Within that, your top level folder is the year, next level below is each month. Each blog post within a month corresponds to the “scene” level. Here’s a link that gives you a visual: http://allindiewriters.com/free-scrivener-template-for-bloggers-manage-a-single-blog/
Entries on the corkboard screen give you an overview of a month and can show when a post is scheduled or if already posted. Here’s a visual on that: http://traceyambrose.files.wordpress.com/2013/04/blog-planning.jpg This author got pretty fancy with Scrivener, using color codes and such, but you don’t need to do that.
I just read about this last week and plan to start using it this weekend. It’s so much easier than keeping a list in Word or Excel!
