Note: I'm already registered to receive iAVS push updates but trying to click in the button just to see what happens... :'(
It is simple - it opens web page on our web where you fill the information to get the iAVS e-mails - nothing more or less 
Ok, Pavel, thanks. I've already did it...
But why is there an error into Simple User Interface?
Btw, could you explain if k@rmas has 'expiration' time, I mean, the user just lost his profile or somebody who 'hates' him could just send him from 59 to 39 in just one day :'(
