Blogs In Network Php include & Function?

Hello

I activated the EDU blogs theme which is super cool. But I was wondering how I could add a function it has to my other themes,

" 4 Blogs in network " < ----- on my other themes

Can you tell me , or anyone help me with the php include and the function,

Maybe there is a plugin or simple code that I can drop into a theme to display this?

Any help is much appreciated

God bless
