right now I'm building a helper plugin to make it easier for me to do simple tasks, such as registering post types. When doing this, i'd like to use some of wordpress base translations. Wordpress has the string 'Add New', which is translated in to other languages. Now, is it possible for me, to utilise the base translation, or will i have to re-translate 'Add New' for all of my post types?. Does wordpress have a text domain, in the same way plugins do. like __('Add New', 'wordpress'). I tried just adding __('Add New'), but that doesn't work either.
Worst comes to worst, ill just have to retranslate it - just seems silly, if i could rely on normal wordpress-strings.
