How Restore DELETE Blog to WPMU

Hi Everyone,

I had a programmer remove the ability for users to delete their own blogs.

Now I want to restore that functionality to users, but have no idea what the programmer did to remove it in the first place.

He was supposed to just remark out that section so I could restore it if necessary, but he never left documentation on where he did it.

Can someone tell me:
1) Which menu / sub-menu a user would click to access the delete blog function
2) Which script(s) would contain the code that my ex-programmer modified?
