Nice suggestion. Actually this has also been practiced earlier but there are few problem in this too. In past when there was no procedure of activation email being sent, most of the members have provided wrong email ID during registration process. Beside this, nowadays, there are few members who have just registered for fun. What they do? They make an email ID just to get activation link to register at PW and then they never check that email. So it is somehow practical and somehow its not.
I agree that there should be some proper way to notify the member. Within few day PW is expecting a "big change" by the development team (which is even hidden from mods). Let's hope we get something good for good
Just a quick thought dropped into my mind. Suppose i m blocked, i don't know why im blocked. The next time when i sign in, a floating pop-up window appears suddenly telling me the details of my block. Practical? lemme share this with admin too
