I will summarize it:

1. No Mine pools. Coin can only be mined via individual computers (about 1 coin per four hours).
2. You can get more coins with Proof of Stake (POS: a form of interest, you get for synching your wallet with the network).
3. PoS used to be very high due to error, leading to trillions of coins (43 trillion) instead of the initial 1 billion. This is fixed now.
4. The value of CENT decreased a lot due to this, but since the stake problem it has started to getting buys again)
5. 43 trillion might seem a lot, but the coin is not devisable, so you cannot split it up like other coins. A bitcoin can be devided into 100 million smaller units, "satoshis", but CENT cannot do this. If you would compare the 43 trillion of  this coin with other ones in terms of number of transferable units, you actually should divide the amount by a hundred million. This means it actually has 43,000,000,000,000/100,000,000 = 430,000 coins (compared to Bitcoin)
6. Currently you can only buy them for market value at Cryptsy (with Primecoin), or via Swisscex (with DOGE).
7. The coin wallet has different versions leading to different blockchains. It is unclear when this will be fixed.

Hope this helps
