My b2evolution Version: 1.10.x

Hello all.

I downloaded and studied b2evo to the point that I'm ready for the forums :)
After installing Autoblog (by Francesco Castronovo) I'm faced with the situation that there's no decent homepage that shows blogs of users (group "Autoblogger Blogs"). The homepage might include a search function for users' blogs, latest posts/comments by bloggers, most active bloggers and their blogs, etc.

I have found no such plugin in the repository so I got to the forums. I am positive that it's possible to write the code necessary to do the above requirement, but maybe someone else already done it?

If no one had already done it, then a little guidance on the following subjects would be wonderful:

1) how to get a list of new recent blogs?
2) how to get a list of new recent posts/comments and their respective user/blog?
3) how to get statistics about: active bloggers, active blogs, active post.

Thanks in advance!
