I have mined on both http://summercoinpool.com/ ,  http://sum.ghash.org/ and both pools for hours and hours of mining and I have given up on them. No response after contacting them. It has been about 4 days waiting for Summercoinpool to pay out and now the same with sum.ghash.org and nothing !    So beware. If multipools are going to be this slack, the coin will keep dropping, PoS will end and so will the value. Very disheartening.   Goin' down fast...
