Olá galera, um amigo meu Usa um Site para world of Warcraft !
Que está com um BUG meio Chato.
Ao player se Cadastrar o site tem que enviar um e-mail de Ativação para que o Player Possa Ativar a conta, Assim evitar que fiquem usando o mesmo e-mail em muitas contas !
Então acho que esta com Algum BUG no Envio de Email ! Estava querendo Concertar, mais meu conhecimento é Muito Leigo !
Alguém poderia me Ajudar nesse Script ? Ficaria muito Grato !
