Hey! I'm not sure you're looking for feedback for the site as a whole or certain features, but here's a few things that I've found kinda quirky:

• The initial render takes a loooong time. Even for the loading icon to show up. The first time around, I thought the site was down.
• I get the following error when trying to create a shop ER_BAD_FIELD_ERROR. Unknown column 'ch.media_id' in 'on clause' (500)
  • The English is... off. (I'd be willing to help with that, btw :D. Hit me up at beetheking@vivaldi.net)
• Usability-wise, it makes more sense to be redirected to the login page after confirming your email, rather than the sign up page. (I got a 'session expired' message after confirming my email, btw).

Otherwise, interesting idea. I'd see myself using it once it comes out of beta.
