More detailed information will be available on the coin's launch, with a 1 week period where block rewards are phased in. It'll be somewhat similar to the original MemoryCoin, so if you can't wait, you can read about that on the BitCoinTalk forum thread.
For now I just really wanted to advise ProtoShares holders of the distribution block - 32000, by my calculations this should be in 2 or 3 days time.
