Why am I not eceiving emails sent to me by Yahoo Answerers?

You probably accidentally clicked one as SPAM rather than deleted it. That is the usual reason for this. Try checking your BULK/SPAM folder or TRASH to find an old one, open it, and mark it as NOT SPAM. Also, check through your BLOCKED ADDRESSES under Options to see if you can find it there. It comes in as "answers-alert@cc.yahoo-inc.co... If you find it on the list, delete it from there. Also, add the address above to your address book for safe-keeping.
