Edublogs theme Edit

I have installed Edublogs theme.

How do I change the links, I mean how do I edit the home page.

Unlike the wordpress, I cant find the edit theme in WPMU. where do i look for it?

I am sure you may have covered this issue, however, I am unable to find it in search.

If you can point me in the right direction it will be great.

Also, is there a way to edit the number of blogs showing or remove altogether? because, if you are getting started, it is just not very impressive for new signups to see you only have 8 blogs on your site.

thanks for you help

you guys are awesome.
