What does nofollow attribute to URL BB Code Do?

[Drache]

Hi can anyone tell me what does

nofollow attribute to URL BB Code in the vb4 bbcode settings do?

Also URL nofollow domain Whitelist ?

Does it mean if I put down some domain.com names in the whitelist then it will make those domains not clickable?
