Who does the Bio Approval?
Is it just one person, or is it multiple people?
And how long will it take for it to get approved:|
That I know of it cali, mugi and zen, Cali being the most common to approve them. Nexus does under certain situations such as a medical nin student, Rei does too but I'm not sure when but I think cali had his approved by Rei. So maybe it's mods only that get their bio approved by her.
The amount it takes depends on when the mod or admin gets time to approve it. It's the holidays right now and for some there was exams before that so they want some R&R.
So you will just have to wait young one.
