I do not think you can make a donation topic for you because that would be begging. Afaik other members organized the donation for yahoo and it was not a formal thing but something some members did out the kindness of their heart. I think it helps that yahoo is a long time member who has contributed a lot and they were not looking for the donation at the start and only did because people wanted too. I think if they opened up a topic looking for donations it would have been removed by the mods.

I hope I do not offend but this is your 1st post asking for a donation from a newly created account will certainly be removed. Yahoo has 1 of the best reputations on the forum and has been a member for years and does not need to provide proof because other members wanted to donate to him before he put a address in the topic.

yahoo posted the reason https://bitcointalk.org/index.php?topic=5430104.340 they got told by a mod to remove the address so I guess it was not allowed.
