How do you lock a question??
um, you can't.. you're not an advisor or administrator. you can't delete questions either, but you can mark them as anonymous so that they don't show up under your username.. just go to your profile then click "my questions" and go on from there.
I'm pretty sure it has to be a really popular question that is very common and has many answers.
its not possible unless your an advisor
oh ok thanx :)
