I think the official pool had some problem I'm mining at 3 ghs but I saw only 700mhs there and also 0 blocks in the last 20 mins. And also the last block was 80 mins ago?
Please choose the correct port per the difficulty:
3008: 8
3333: 32
3256: 256
3004: 512
3005: 1024
3006: 1536
3007: 2048
3018: 3072
3009: 4096
Thank you!, I'll be sure to update the getting started page with this information too.
