I would question using Yahoo email. My roommate and I came up with about 5 people, all Northern Cal whose Yahoo email accounts have been hijacked to use for SPAM, four recent incidents. I would suggest that you might want to change your Yahoo addresses if you are a local resident to something else.
I have had success with Gmail. It's useful, particularly if you have ATT or Comcast, or something like that and have to change your TV/ISP providers occasionally due to changes in your entertainment-phone system on-ramp services for new residences. It helps that using Gmail means that you don't have to keep sending your contact list an updated email address. Don't tell me about problems with Gmail . Nothing is perfect. Just sayin' it is happening at an alarming rate locally.
