In your profile under preferences, you can set the style.
There are default, electronics point (old) and maker pro retro.
The box does not show in the "maker pro retro"style.
The box means to indicate the join date.

The square is a four-sided figure that has always been used to represent the attributes that are associated with the number four. In Sacred Geometry, the square represents orientation and direction, in contrast to the circle, which symbolizes limitlessness.
Huh? Whazzat? I learned about Euclidean Geometry in high school, and non-Euclidean Geometry in college, but wtf is Sacred Geometry and who says its sacred? Does this have anything at all to do with religious faith or electronics?
Oh, yeah... and welcome to Electronics Point... er, Maker Pro, @willsonwanda.
