Urgent: How to change webmasters email?

[digif]

I'm active one year, and just realised my contect form doesn't work - doesn't send me emails.. where do they go?

How can I change webmasters email, or the contact form email where the messages go?

Please help,
thanks.

Sorry, the email is set up on vB options, but, when someone send it to me, I never get that email, why?

I found the answer, it was mistake by hosting provider.

Thanks anyway.
