I just got an email to my yahoo account inviting me to join a website called hi5

It pretends to be a group/personals service - don't click on any links, don't join, just ignore it - delete it!

It's a scam - looking for emails to sell and you will get tons of spam from it if you give them any information.

I also found sites that claimed that the hi5 website tries to get you to give them your various IM account names and passwords. Be warned!
