Im looking at using MacJournal for keeping a personal journal and also for writing my blog posts. The interface for creating entries in Word Press is rather “industrial” in its feel. MacJournal has a very clean feel to it so I think it may work well. However I dont know if this will get posted correctly as cant tell for sure if Word Press is supported. As I am writing this post in MacJournal I’ll find out very soon if it works or not!! 
It worked!! I used the default settings for Movable Type in the setup and it appears to have worked great. I’ll try attachments a little later but for now Im back to fiddling with MacJournal.
The Mariner Software folks (Owners of MacJournal) are all very good friends of mine and I have been using the product for years. If you run into any issues or questions please feel free to let me know.
