[TYPO3] Communitys - what's possible?

[Andreas Balzer]

Hi!
I wanted to ask, what is possible with Typo3 to create a community?
So like board with chc-forum, blogs with timtab, etc..

What interests me most is, what is possible with what extension so that 
you have one big community that can do all of that stuff with one 
account per user (and not one for a calendar, one for a board, etc..)

FE Editing would be fine..
