Mintpool seems to calculate the hashrate incorrectly. I'm pointing 6.5 mh/s since last night (3 different miners), for last 6 hours, still it shows as 4 mh/s

Why does cgminer not work? Other multipools support it without problems. I would have switched much earlier if it worked, there isn't much information on the website that cgminer doesn't work -- I had to find sgminer and use it for the first time. If you can get it working, I believe you'll have much less resistance for people switching over
