Customize the error message

Hi,

I’d like to customize the error message.

People don’t understand they have to be friend with someone to be able to send him/her a message. So they get upset because they spent time writing a PM then think that there’s a bug. Some even create another account due to that and of course have the same thing happening to them.

Is there a way to customize the error message or at least to be able to have another error message?

Best Regards
