(TEMPMEM) - Torne um membro temporário
Tempmem allows main owners, owners, and moderators to promote guests to member for any duration of time, up to 24 hours. Note that you must be a moderator or above to use this power.
Temporary members that are signed in while their member rank expires will remain a member until they sign out and in (including changing name, avatar, and homepage). They will become a guest afterwards.
Uso
Start a private chat with the user that you want to make a temporary member and type /mb followed by the duration of time you want them to be a member for (in hours).
Exemplo: Digitar /mb12 no bate-papo privado de um usuário iria tornar o usuário um membro temporário por 12 horas.
