I don't necessarily want everyone seeing everyone else's IP addresses all the time. i don't even want to see them myself unless there's a problem with a user.
just turning them off via css is not enough. i don't want them in the page source either.
i had a user ask me about removing this today because when you google their IP, the number one result is a post by them in my vanilla forum. then you click their name and it displays their name and info.
it should be an option to remove. only admins should be able to see IPs....
