PivotX is free (GPL licensed) and can be flat-file, which is what I need.
From what I can tell it can also give me permalinks for posts, and I can include image(s) in posts.
I also want the following though, and I'm unsure if PivotX can deliver:
- Allow for multiple editors with non-admin rights.
- Not require command-line access to install or upgrade.
- Allow visitors to login and comment on posts, with comments being saved locally. (Not via Facebook/Disqus/etc.)
Thank you in advance for feedback!
