Thanks to @lorenbaxter's suggestion, I've enabled logging in with email rather than username if you prefer. Luckily Drupal's logintoboggan module allows admins to offer this option, as well as offering registration and signup without the roundtrip to email. Sweet. Thanks for making my life easier, Drupal.
This should help ease the experience of finding your file downloads as well if you bought stencils or icons form the store. It also brings me around to re-implementing some of the features I put in in Feb-March last year and then took out, e.g. vote to promote on design and interface submissions. I have a minor redesign planned that hopes to bring that back, but will bring it back for signed in users.
