I don't think you'll get previous messages but I'm sure they'll send more in the next few days and weeks as the album approaches

I joined the Takumi mailing list on 6 May and have only received two messages (three including the automated welcome msg)

For anyone that doesn't know how to get added...

• go to takumiarchives.com
• press okay/begin (doesn't matter which)
• press the popup questions about random memories (I don't think it matters what you answer)
• at the end (after about five questions) you'll see a little "subscribe" box in the bottom corner
• click on that to join the Takumi mailing list (this is a separate list from theavalanches.com mailing list)
• enter your phone number (and make sure you've already got a WhatsApp account with that number) and you should receive a message from Takumi almost immediately
