but how did you know that i want to mine macd coin when i use my privatekey as username ?
Because MACD is currently the coin that is being mined on the X13 multiport. That will change as the purpose of our pool is to mine coins upon release and move on.
Follow our twitter as well for updates. @FlashMineCom
is it possible to use my macd adress as username , like anywhere else ?
No you must generate a key.
Regarding the question above, please see the information right at the top of the Key generation page. "This script run client-side (in your browser). For maximum security download the script and run it locally and offline in a modern web browser."
Once you have a key generated, you can obtain the private key to import into your wallet.
