Personal Blog for each users.

Hello,
I just install easyblog on our dev plateforme, and i'm little confuse.
When we have check this product, we were really happy to find a nice blogging system with a lot of things we want.
And one of the think we want is to offer "personal blog" to each users of our plateforme.
By default this "personal blog" will not exist, the user must "create it" by an action on his profil for example.

The goal here is not to have a new instance for each users, but to be able to offert a specific url for their posts.

But so far i didn't see how to do it.
Is it possible with easyblog, and if yes how ?

Thanks for your help.
Best regards.
