Post requirement phrase change

[akoj]

I have a site for kids and they find the post requirement error phrase a little confusing. I cannot find where to change this. Does anyone know?

Search for the phrase in the relevant lang file (/arcade/lang) and simply change it to whatever you prefer, save and re-upload.
