PowerJournal is a Scripts software developed by Chris Arrowood. After our trial and test, the software is proved to be official, secure and free. Here is the official description for PowerJournal:

EditByMarydown: An easy to use Journal/diary application. Features include: Multiple journals, Private entries, Guest mode access to public entries, Built-in database (hSQL), Supports MySQL, Easy installation, Available for Windows, Mac, Linux, etc

Maintains a database of entries in a journal-like format. The user can add, edit, and delete entries. Each entry is timestamped. Easy navigation through the entries is provided. I wrote this for my personal use but decided that I would make it open source so others could benefit by it. I had been using Microsoft Access as a journal and it met all of my functional needs. However, it was not cross platform so I could not use it on my Linux box. Also, I have been trying to break my dependencies on closed source, proprietary software. Thus, PowerJournal was born.
