Thanks, I am trying WeMineLTC now.
I wanted to try Hypernova because of its CPPSRB system.
However, when I typed in my payout address, everything changed to ALL CAPS. I thought the address is case sensitive, so I don't trust it.

I got very low hash rate with my 7870 tahiti. People say you get 1/1000 of your bitcoin hash rate when mining litecoins.
I got 500 Mhash/s in bitcoins with a slight overclock. However, I only get 350 khash/s with litecoins. Is it normal?
