When do you have RC up?

[pooper200000]

I was talking to someone about this the other day. When do you think RC should be up? I know this can vary depending on what staff position you hold also.
GP's might want to leave their RC up if they are the only ones with ban rights in the case of a hacker. Should you only use client-RC or should you have regular RC up?

If you can list what types of staff should have RC up, or client RC, and how often.

What is the most appropriate usage for each?
