Well, it depends who's asking. If it's Madame Frufru, the sex-pot GCSE French teacher, asking me to do her homework, then I might be tempted to refuse, on the off chance that she'd then put me across her knee and spank me.
Seriously, though, knowledge is acquired in many forms. Asking those who are possibly better informed, if only by virtue of them being older and therefore further along on life's educational path, is merely one of these forms. I see nothing wrong, therefore, in soliciting information from the contributers to this site. The questioners ought to have the decency, though, to acknowledge the help by thanking people and also, where appropriate, cite the source of their information in their assignment.
