Is that your miner software telling you that or the website? If it's your software, something is wrong. Are you sure it's not 1.4k, not 1400 k? If it's the software, PM me your username and let me see if I can see what's going on. You're right though, pool is at 1.5 Mhash and it's not all you that's for sure.
Username is P4man, same as forum name. Here is a screenshot:

Pool stats also look weird to me... getting 1-2 Khash on my worker page and most blocks I dont seem to get any shares, but I have no idea if thats normal or not.
Wrong algo... Should be scrypt...
