Hi Laurent C. Welcome to the forums.
Straight out of the box, b2evolution does not do that. It is not meant to be something like blogger is why. It is, by design, YOUR multi-lingual multi-blog multi-blogger application, meaning the owner of each installation decides who gets what permissions in any and all existing blogs. I'm pretty sure the owner of the installation can set it up such that a blogger can create a blog, but not with a single click option.
A long LONG time ago there was a hack that gave people a blog upon registration. Then a long time ago someone else turned that hack into what was possibly the most popular plugin of all time. Now however no such option has been crafted out of aftermarket tools for the latest and greatest release. I've heard tell of it being "in the works" but I've no idea when such a thing will happen.
