Very useful but…

This pug in permits great things. I used it to build the Private Area of my website.
You can create new users, new passwords, different looks to the same page or blog.
So, I’m very happy about what I can do, but it’s very fragile.
After an update it always work with the past articles, users and passwords, but you have to become mad to discover how it changed and which is the way to do the new works.
