I don't speak German, but I understood the question.

B2evolution is a logtool
it is even more
it is a log engine

it is a "Multilinguale Multiuser Multiblog Maschine."

But DON'T install the version you can install trough cpanel.
Download the latest version 0.9.0.10
It far more better and polished than 0.8.7

es ist ein weblog, also kein portal-tool.
