The Remember Me checkbox does not work.

Every time I visit this site I have to log back in, although this is not to much of a hassle since I use Last Pass and all I have to do is hit login and it is done for me it would still be nice to have the Remember Me checkbox actually work. This applies for both when I use this site on my PC and my Phone, just in case this is a browser specific problem that I'm not aware of, the browsers I use are Firefox for my PC and Chrome for my Phone. Although this is a very very minor gripe with an otherwise pretty awesome site, I'd just thought I'd see if perhaps anyone knew a solution to this issue to make my experience pretty much perfect.
