At first glance it seems to do what I need – providing the option to create new posts, edit old posts and assign categories and posting date to entries. If you can see this post, then it would appear to work.
I’ve been investigating the options for updating my blog offline, and as ever, much of the available software is only for the PC. I’ve decided to try out ScribeFire, an add-on for Firefox. My hope is that whilst I’m in Antarctica I can prepare blog entries and publish them on my return home, rather than trying to play catch-up.
