Community site framework suggestions

in the holidays break (and probably for longer) I'm going to program a community website for my sports team.

I'm not very keen on the frameworks available and I'm mostly looking for something that's both simple, fast and flexible.

I have a few requirements:

1. Easy user interface.
2. Creation of events so users can sign up for them.
3. Point/reputation system so use开发者_运维技巧rs score points for showing up on events.
4. Suggestion system, users come up with ideas for events that get up/down votes.
5. News that users can comment on.
6. Forum (not necessary).

I think that sums up the biggest part of what I want to do. I know this might take longer than just the Christmas break and I'm ready to learn to get things done.

Thanks for your suggestions in advance.

Drupal comes to mind. There are modules for every requirement you listed.
