Remove "Powered by vbulletin"

[richards112]

Hello, i was just wondering, how do i remove the "powered by vbulletin" from my forum.
For example it says: your forum powered by vbulletin.
How do i remove this?

And if i may quickly add...

How do i remove the vbulletin version from my footer???
It says powered by vbulletin version 3.7
How do i just make it say, powered by vbulletin.

Advice would be appreciated
Thanks.
