eJourn is the style of program which, instead of operating on files which you are very aware of, attempts to hide its actual storage and track everything for you. This means it's not so good for generating documents to send to your friends; but better at keeping documents for you to find later. Other applications with this style in mind would be Picasa and iPhoto for photo's and itunes and others for music.
Here you can see the first window eJourn should open. The first thing you MUST do is create a new journal. If you click close, or cancel here the program will close (not nicely, but that's ok).
Choose Encryption here if you'd like to be prompted for a password to view and edit the journal later. If you don't choose encryption you will simply be brought to the main window and you can skip the next part.
This next window is so that you can create a login for this journal. Again, hitting cancel here means exitting the program. So, to proceed: Type a personalized message in the text area. This is of moderate importance. Make it fairly long, at least one sentence (I recommend making it more than 256 characters, while this is about 80 in parenthesis here).
Next you need to enter your password twice. It will only show the Login button when your passwords both match. Once you click Login you can edit these things in the preferences under the edit menu.
This window may or may not popup after you click Login. It's actually not supposed to, but don't worry if it does. It won't hurt anything. Just type your password in and hit login.
As of this writing this window is actually popping up multiple times on the first use. Apologies for the bug ;). I'll go file it right now!
