About messages, I try to send message with 0 NXT fee or 1 NXT fee. But I can't send them. (No response when clicking send.)
When attaching a message to a transfer, I got such info:

@miramare ok, got confirmation that only hex works for messaging on testnet! I will remove option of sending plain text!
