this will need to be a translation string ... little bit tricky. 
we could do an interpolation (e.g. `t(:discover_thing_on_loomio, model: t(:disscussions))` ) , but it might be a confusing case for translators unless i get in transifex and add a comment explaining how it's going to be used.

rather than interpolation it might be easier to translate who strings then have a case clause
