Do you have any video about edublog inside? I know that

Hello
Do you have any video about edublog inside?
I know that this is big and powerful network. If you have somewhere video explaining how edublog network works it would be awesome.
If you do not have, maybe you can ask guys to record quick video about edublog inside and its structure. I think it would have a lot sense for us to see how big network of blogs is setup and how it works. I am pretty sure I can have a lot ideas how I can setup my own network of blogs.
Thank you. Ivan
