First of all, I would like to say that the interface is nice, amazing, and user friendly!!
Thanks Dani and those who work hard on this !!!
But one thing I would like to comment is about the vote and comment. It seems like only users with high reputation allow to use this feature because I get this message when I click the vote up button
You do not have the permissions required to access this page.
Would you like to go back?
Since this feature is not available to all users, why not just make it visible for those users only ?
