Where do I submit a possible bug?

I realized that the "remember me" option in the login does not seem to work. I was thus wondering where should I post this? At /t/ideasforsnapzu? Is there a tribe only for this purpose? Or do we send them en email to a "support contact" email? I apologize in advance if this question has already been asked, but my poor search did not find anything.

P.S. I only tried logging myself with Google Chrome
