Another vBulletin question

For those who have skinned or know how to skin is there like an easy way to do it? Man this is outrageously confusing. Is there like a guide or a site. The manual does not really cover it.

I am asking here because vbulletin has indeed blocked a large block of ips and mine falls in there. So till they get that fixed and is off limits to me :frowning:

So any help greatly appreciated.
