I can login and see my balance, then when I try to alter my account information and enter in the correct PIN i get kicked out and my account is locked again. I can't see any prompts about the PIN being incorrect.

Can you please unlock my account: Mikebrisboy

This is getting ridiculous. I mined a heap of coins and then when I went to alter my payment address my account got locked!

Hi,

Thank you

A great website to keep track of merchants who are accepting bitcoin and litecoin is: http://coinmap.org/

Another coin you could mine with a CPU is Quarkcoin. Otherwise plug some numbers into http://www.coinwarz.com/cryptocurrency and see which Scrypt based coins are profitable for your GPUs to mine.

While you're at it, I would also recommend following the most popular coins and their market caps at coinmarketcap.com.
