Really, cause what's the difference because I just want to use a more useful backend and it is for my personal use. I can tell you for a certainty that I will not be able to get in touch with the creators. I have tried. It is a group that has a web site and the people who participate as part of this group changes continuously and they have no contact us info anywhere. So I don't get it.
If I could use the theme for my own personal use for free why can't I just attached a different and more useful back end to it. Wouldn't it be more about using/showing the footer credit link than anything else?
