There are several users who don't feel comfortable using the standard Drupal interface to create content on their website. I've noticed that this is the case with reforestation.net, I site I manage: even though I provide users with accounts and training, almost all users end up sending me their content (including images and text) via email, and I have to upload it myself to the Drupal site. The main reasons cited for not posting content to Drupal are: it's too complicated, connection too slow (especially in Africa and the Caribbean); and it does not work as expected. So much for end-user empowerment! The one technology with which all users feel comfortable with is email, so I set about figuring out a way to get users to be able to post content to the site by sending an email (or rather, for now, sending it to me and me forwarding it to a special email account created on the site).
