Which CMS for a blog-forum social network to choose?

Question

CMS

The fact is that we need the functions of both collective blogging and the functions of a full-fledged forum. There is no need for bells and whistles. I need an engine for collective blogging and forum communication, and even with a relatively small load.
So far I've looked at the following options:
LiveStreet - I liked it, but there is no full-fledged forum.
Wordpress + buddyPress + bbPress -- a huge load and very crooked work of templates

Answer 1

Their mules!
The same Vanilla with the necessary plug-ins - flies.
But a noob with crooked hands, most likely, will not succeed.

Answer 2
