I know the developers don't like this, but I wish there was a way to remove and/or edit the "default created by" message from the footer without having to modify the code and recompile it myself. I'm really don't know enough to do that right now.
This can be done using the current version by including a footer tag in the XML file.
The end of the file should look like this:
<Footer>This is the footer.</Footer>
The next version will have an option in the menu that will let you change the footer without messing with the XML.
