If I have MtGoxUSD then MtGox will allow me to withdraw it into my bank account into BankUSD.  MtGox basically guarantees this and this is why MtGoxUSD is "valuable".

If I have BitUSD who will allow me to withdraw BitUSD into BankUSD?  Is this a service that needs to be built?  Or is BitUSD only backed by BitShares?   It seems like if I own BitUSD no one will convert it directly to BankUSD without first converting it to BitShares.

Since I can convert MtGoxUSD into BankUSD easier than converting BitUSD to BankUSD, it seems like MtGoxUSD is more valuable than BitUSD.  Your thoughts?

I mined 50 PTS but it was not accepted (Unconfirmed 0 of 6 confirmations.  Generated but not accepted.)  It was mined three hours ago and I have 8 active connections and it is up to date.

Can you also give instructions on how to start the mining process?  Thanks in advanced.

So for the launch is the minimum RAM 768MB?  Or is the minimum 758MB + 1.5GB?
