I only received my tokens today. They have said on Twitter that they aim to have 60% distribution complete this week which means 40% still won't be distributed this week; hopefully next week then.
The 100% bonus emails going around at the moment is a fairly obvious scam - do not interact with it.
Did you send in a screenshot of your transaction?
Yes, I sent a screenshot on January 25, they sent me an email acknowledging this on January 30, then nothing until I received the transaction on February 17.
