Yep, my GF and her DH are happy for any resulting children to turn up on the doorstep in 18 years to get a sticky at where their DNA came from and they have also explained to their children that mum has donated her eggs so other families can have kids.

As a side note, both my GF and her DH were required to undergo counseling as part of the criteria for acceptance as a donor. I was surprised her DH had to attend the counseling also, but I guess it makes good sense!
