Sign-up dialog doesn't fit mobile screen

[CarloK 201]

Browsing the forum on a mobile screen but not logged in, then there pops up a huge dialog that suggests to sign up. The dialog is too big to fit a vertical screen (1920 x 1080 resolution). Please remove or resize the large ulti robot graphic so the dialog fits a standard mobile screen again.
