I've tried to change the template name using your guide. But the header of the web becomes "crazy". The logo has been duplicated (or something simillar), and the format of the page changes. There are a pair of instances of "gk_events" in .js files that I'm not sure if it's neccesary to change (seems to be URL's). Anyway, I've tried both ways, and both fails...

I am in the installation phase yet, no URL to check, sorry.
Sorry for my poor english.
