General Questions

I have just installed Gallery and am excited to start work on it. I have a few simple questions for Gallery. I can't seem to locate an exact answer in the documentation. I am an avid amateur photographer and want to link my gallery with my web sites. I do not wish to create a community of photographers. I have the administrator approval of new users selected, but is there a way to just forbid the registration process altogether? I have a number of pictures myself and maybe, sometime in the future, will also pair this with one of the e-commerce tools. I have three web sites altogether and no staff so I am very busy without the duties of maintaining things for a number of people.

Any help will be greatly appreciated.
