WordPress MU

Hello,

What is the easiest way to redirect certain subdomain blog?
domain: example.com
blogs:
one.example.com
two.example.com

I want to redirect two.example.com to just example.com. In a way disable two.example.com for a certain period of time and in stead of displaying disabled blog to redirect user to some other page without him knowing two.example.com is disabled.

Which files should I look into. You don't have to give me solution, just give some hint.

Close it please. Found wp-settings.php "spam" variable gives 410 Gone which is perfect for modifying.

If anyone wants a fix for this, there is this thread:

Could have sworn that there was another thread, more recent than that that also had some ideas but that should get folks started.
