I am new on SP 2010 and VS 2010. After installation of SP, I am able to surf to localhost, and see a page called "Home". I made a test Visual Web Part, and it deployed fine. I am able to edit the home page, and see and add the web part from the Custom folder.
I then made a new site, called Foo Site. When I edit its home page, I do not see the web part Custom folder, so I may choose my web part and add it. Why does the Custom folder show up on one page, when adding a web part, and not on another?
