Por favor , nada de UP nos tópicos, e URGENTE não é um título bom para nada, se quer facilitar para que te ajudem, coloque um título condizente com seu problema.

Nossa fiquei impressionada com tanta educação,pensei em ficar quieta mas achei vc tão delicado e sutil que seria uma pena deixar passar em branco.PARABÉNS!!!
Se pra vc URGENTE não é CONDIZENTE,desculpe me,mas pra mim é.Agora se acha que não fica bem para um titulo no forum ai…tudo bem,deveria ser mais especifico ou ficar quieto.Bom acho que fui tão delicada quanto vc infelizmente.

desculpe minha ignorancia,mas o que é UP???

UP é o que você fez quando postou um smile.

Você simplesmente postou qualquer coisa para o tópico voltar a frente, ou acima, sei lá!

Se não há, deveria haver nas regras do forum algo que proibisse topicos com titulo do tipo POR FAVOR ALGUEM ME AJUDA, ou então URGENTE (ESTOU ME BORRANDO!).

Para o autor do tópico uma dica. Esse tipo de titulo nem costumo me dar ao trabalho de entrar pra responder, e acredito que muitos fazem o mesmo que eu.
