How to select the most helpful opinion for questions?

[Anonymous]

if i don't select the most helpful opinions then will they get selected themselves?

[tacoty21]

you have to close the question before you can pick the MHO. also your question has to be up for at least a day=24hrs before you can close it. The MHO only is chosen if you pick it

can i unrate an opinion as most helpful opinion?

[DaddiesLittleToy]

No you cannot

[tacoty21]

even if you could why?

[Asker]

i didn't select a question as MHO but somehow it appears as mho...

[DaddiesLittleToy]

it will do it automatically if you never select one

@DaddiesLittleToy oh :(

How do you close it

@DaddiesLittleToy that is the problem, how to un check this option. I find it really annoying that it auto selects.
