@muru Y,YRC ;-)

Another way would be changing the password of your account and send the credentials to a moderator. Once the bounty is assigned, change it again.

@MarkKirby: Yes, it would be another way of cheating the system. However, I think that SE doesn't support bounty control transfer.

Maybe we can simply mass-upvote the answer you want to award.

@Dan: Ok, now I understand it. I edited my answer. Plase check it.

I've already converted my answer into "community wiki". I included another answers because mine is soo long and with many points, and all the other answers are really "hidden" at the end. So I don't mind to use the rest of answers to "profit". However I don't know if as Mateo says (in a rude way indeed) is unethical yet, even as a community wiki.

@muru: Please post your recommendation as an answer ans I'll accept it. And please, Mateo comment and give your opinion.

@Mateo: Now I remind that I checked Community Wiki box as muru suggested. Before now I don't knew what does this, but now I had a bit of curiosity and googled it. Now I can't undo the Community Wiki nor recive upvotes, which is a great thing, for me as I can include answers from other users, and fo others, because they can edit my question to improve it instead of making other. You don't noticed that detail and your coment is offensive.
