you're not the only one with this problem - took client weeks to get me the efile signatures back - received yesterday and I efiled. Came in this morning to a reject for a kid claimed as a dependent on another return. Not the first year we filed for them but I've checked several times that the ssn number is correct. Same as prior years, etc. Mom and Dad are the parents - no remarriages - 

just waiting for a decent hour to call them and ruin their day as well 

so yeah Ugh and Double Ugh
