Should I trust this? And give out all the info they want?

NO, what you got was what looks like to be a scam email using the Yahoo name to lure you, they do this because mostly everyone know yahoo and automatically trusts the name thinking its secure but in reality its the opposite, I'm gonna tell u this to always remember, any emails u get that asks for any of ur personal info, ITS A SCAM!! 100% so if i were u take this email and send it to the webmasters of yahoo and ask them if they are aware this is being ped thru to people, they will look into it and possible stop a lot of people from voluntarily giving out their info. This is a perfect recipe for identity theft. Never give ur info out unless ur on a secure site like ur personal bank, pay pal, etc... not a bate and switch site. Good Luck!.. P.S Whenever in doubt, DELETE!!! Bye, Jessy
