I am also trying to understand the private key thing.  So, you want us to leave our neblio in the QT wallet while entering the private keys to that wallet on a website on the internet?  This makes absolutely no sense and does not sound safe at all.  I recently participated in the Litecoin hardfork and did almost the exact same thing but you at least moved your LTC out of the wallet, then handed over the private keys.  After that, they told you that wallet was no longer safe to use and was a good idea to delete it and install a new one.  This doesn't sound legit and sounds dangerous.  I have over 300 nebl and want to participate in this airdrop but this is sketchy...
