I'm the chief administrator at
https://BitForwarder.com. I see that one of our employees (btcspry) has contacted you about this opportunity. I would like to personally talk about the opportunity proposed here, as I think it could do wonders for our business. Could you PM me so we can further discuss?
I second this. I made a post in the thread, and I have a gut feeling they are trustworthy.
However there is a problem with that type of website, and that is it will NEVER be able to be 100% trustworthy, because the private key will be given.
