I'm a little confused by how to use this coin.  A few questions - sorry for how many there are.

1) Do I get more credits if someone votes for a card that I created and voted for?
2) Do I get more credits if someone votes against a card that I created and voted against?
3) What happens if I create a card and vote for it, then people vote against it?  Will my vote count ever decrease in this situation?
4) Why did the voting period say 24 days this weekend - it is lower now?

5) If I am a coward and choose not to create cards, how can I increase my votes?  I continue to vote and did a survey for a few more credits.  How might my profile increase?

One last point, how do you plan to build "community".  At one level, I see that a community develops around people that vote in common.  But, how do we interact and converse, etc?  Is PR.NETWORK a starting point for other community tools like facebook?

Thanks for any response.  Good luck with the project!
