As a former unibash test giver/teacher/whatever, I feel like it could work. We closed down for a very large lack of interest from both sides, test takers and the givers/teachers alike. But lately it seems like more and more people have taken an interest in Unibash.
But to the more technical side. Who would operate Unibash? Would it be the same as back then (I.E people apply and get considered), or maybe be made into another responsibility of HS? I feel like having HS operate Unibash would make HS a pretty hefty position, maybe even causing it to gain an actual help squad leader a la admin style. Unibash worked fairly fine when it was operated by people who didn't necessarily need to have other responsibilities, and nowadays it feels like there are way more people who would like to help out anyway.
