I want to trigger a function in a plugin when a new sub-blog is created in a multisite set up of WordPress. Is it possible? If so, to which action/filter should I hook?

The motivation here is to modify the new sub-blog blog it has a preset arrangment of settings, theme, plugin options, plugin activations, content set up, etc.

If there aren't action/hooks for this purpose are there any other ways to accomplish this?

How about use a plugin that does this already? – andrea_r Nov 14 '10 at 13:31

U guess you can use the activate_blog hook

I am not able to find any such hook in the wordpress source code. Could you point out which file it is in? – rsman Nov 14 '10 at 12:16
