Just in case I can’t get on the internet,because i’ve been using the one here.
There’s a nice journaling program by Banhurt, you can download it here.
Besides, most people just create a text file when they don’t have access to the internet, but that’s fine too. 
I’ve been using a software called “Efficient Diary” for a DJ and I love it!
I can’t imagine a better software for journaling dreams. 
Free, secure and very easy to use.
Hey Mars, I just checked out that software you linked to. Awesome.
There was one Dream journal software a friend gave to me a looong time ago. I wish I could remember the name. It was so cool because it had a built in dream dictionary and some other cool organizational stuff.
Oh well.
I’m currently developing a Dream Journal application! So far its going nicely! Maybe a few from the forums are interesting in using it! I’m keeping it very simple yet nice to the eye.
Keep it up FretDancer! 
I’d like to check it out when it’s completed.
