Como ter a opção de usuários se cadastrarem no sistema? E então o admin liberar o seu acesso?
Translation via google translator:
How to have the option of users to register in the system? And then the admin gives you access?
I don’t think this is currently possible in ownCloud.
IIRC there was an app for this once. But now it’s on the ***Cloud side, no clue if it can be used with ownCloud.
