I have read the rules but would ask again, so I can't bake and my cooking skills are also poor. My daughter is still too young to understand Bitcoin (but she already got a
cold wallet and personal BTC address from me) but she can bake pizza. Is it OK that she can participate in the contest without a forum membership through my account?
Well op, I haven't really participated in any contest here on Bitcointalk but I have seen many contest which were done in the past and same questions which have been asked. And I think that there's no need to even ask such questions as nobody will be able to tell if the content was originally created by you. But as long as you were there when it was created and you also took part in the process. I think you can use it to participate In the contest. But since you already asked then you can just give little credits to your daughter in your post as I don't think that it would be an offence.
