That doesn't seem to be safe. Can u at least give your pubkey to encrypt the message? And also it would be good to see this announcement signed on an official website or somewhere? I guess I also need to install a client to provide an address to send Iotas to?
First do the following:
1. Download

2. Run it by doubleclicking
3. Enter your seed
4. Send the resulting address to that email above
