Nowadays, any website that handles something serious proposes it. And this forum is definitely something of that level, it deserves it.
Yes...wholeheartedly agree 2 form authy!...it really sucks to attempt to build a rep, and log in to discover someone found a way to piss on it in your absence. In my case if you do any simple googling...you'll find I am connected to me in real life, so finding out a hacker used my account and posted all kinds of non-sense all over this forum was particularly unsettling...2 form would have probably worked pretty well even if he had gotten my weak password.
