Under the 'new' design, how do you email attachments and comments to an existing card?

[Bill Mitchell]

Under the 'legacy' Trello one of our most used features was the ability to email content to a card including attachments; we don't seem to be able to find this feature anywhere in the new UI and this is a hugely important feature to us.

The card email address is available under "share" menu - click the three dots on top-right and then click "share" to get the secret/unique email id for that card (see image below)
