It's an interesting idea, but I think there are a few technical and financial considerations.
Firstly, LWD would need to buy a new domain name for the email addresses (to say nothing of the expense of text receipt software) so that I could, for example, be
Chemlak@realmworks.com.
Then there's the problem of what format data would need to be in to get it into the Realm correctly.
Presumably, you'd put the Realm name as the subject line, but the body of the email would have to include topic names, whether it's Story, Plot or World almanac, whether it's a new snippet, what category of snippet it is, whether it contains tags (many of which will be user-defined), and to guarantee it would work would need there to be
absolutely zero errors in the body of the email, because otherwise it will need human intervention to make it work. At which point it's easier to just send yourself an email with the details and copy/paste.
Now, a
Smartphone App to do the same thing...
that might be worth looking into. Especially after we start being able to sync to the cloud.
