Blogify is an example of how you can make a blog using the Alpas framework.
I didn't use authentication in this project - though, that's just a couple more lines of code to add authentication for add/edit/delete actions which I'll work on shortly.
Feel free to use as a base for your own blog project or as an exercise to become more familiar with some of the functionality in the Alpas Web Framework.
Check out Alpas Resources for additional resources and example apps for the Alpas web framework.
