Srb2 Community/Crazy Build - Change Camera distance on 2D Distance and Set up Skybox

(I hope the title isn't too long.)

I have two questions.

1. I saw the change 2D angle change Fof in in one of the examples and copied it exactly. In the end, the camera goes very far out. Changeing the lindef size length doesn't do anything..:(

2. How do you set sky boxes up? I see nothing tagged in the examples.

Thank you in advance.

For the skybox, you just need the thing on the place you want. You don't need to use tags.
