Make registration more user-friendly as their main page contains many information. I think it should emphasize action: “register”.
I believe that the user should be able to choose his own way to settle groups and make design for his page (choose the main color schemes). Ability to regulate the number of columns on the page. Every device on which you use Vingle can have own columns settings, for instance: laptop from 1 to ∞, tablet pc from 1 to 5 and smartphone from 1 to 2.
Therefore design improvements:
1. Less ingormation in the main page
