How to find a user on auction onet.pl?

Is there a way to find or browse users on onet.pl auctionsite? I dont remember email or username correctly ,only remember the 3 first letters of the nickname.

If anyone know ,please tell me.

So you only have first 3 letters of the email? Like abc*********@poczta.onet.pl? I don't think there are public @onet.pl email accounts.

Not email ,but first letters of the username.

You can go here aukcja.onet.pl/search_form.php and enter something in this field:

Nazwa użytkownika lub adres e-mail (Username or email address) - on the bottom of the page

But I think you should have exact match only..

Yes ,exact match only :( That really sucks ,one should be able to browse the users, what harm would that do?
