I happened across a site called drop.org today. The site claims...
"Drop.org is an active community of web enthusiasts that exchange ideas and experiences about the latest developments in web technology."
If you try to login, at:
http://www.drop.org/module.php?mod=user&op=login
it says, "Enter your drop.org username, or an ID from one of our affiliates: Blogger, Delphi Forums, Drupal, Jabber, Manila, Yahoo."
I've never heard of any site having a cross-registration with Yahoo, Blogger, or Delphi. It seems like it might be a scam to get passwords. What do you think?
