Access to the i18n outside of a request

[sganz]

Quick question on how the best way to use i18n.__() functionality outside of a request. I have got things working inside of express by following your examples, and all good.

So the question is if I need to use the i18n.__() functionality outside of an express request (where I have no 'req' object) what is the best practice? Just create another i18n instance, or get the existing one from somewhere (app? express?) .

Thanks
