Yeah, this should be implemented. It seems like devs of the site missed this.
Well, i had an oddly, strange bug when creating my account. I used a gmail account to sign up but didn't receive activation email. So, every time i tried to log in or to re signup with that gmail account the site told me that i need to activate it from the mail that they sent me but i never received one. I used another mail and everything worked fine so i guess it does't matter anymore but they need to fix this. Just add a way to resend the activation mail
