I can't get past the installation wizard due to a special database user privilege required.
I'm trying to run this a very typical standard Linux hosting provider called Surpass. I've installed many application with this provider. I've also installed Power Gallery.
So now I have to set the installation aside and wait a few days for support to help me out.
Sorry folks, just venting - but it gets frustrating.
