Versão do fórum:
PUNBB

Olá!

Painel de controle ->Visualização -> Imagens e cores -> Cores
Procure por : Tamanho da Fonte principal : e adicione o tamanho em que deseja.
Salve.

Até mais.

Caro PabloW.

Desculpe mas deveria ter especificado mais minha dúvida ...
Não quero modificar o tamanho da fonte e sim a fonte ...
Ela está Verdana quero Mudar para 'Trebuchet MS'

Olá!

Senhor segue os mesmo passo em que passei na mensagem acima, e acima do negocio do tamanho da fonte, haverá os nomes da fonte do seu fórum, modifique-as pelo o que deseja.

Até mais.

Como eu disse eu ja tentei de tudo e ainda não consegui ...

Adicione isso a seu css :

Código:

.pun h2, .pun h3, .pun input, .pun select, .pun th .hierarchy .forumtitle {
  font-family: Trebuchet MS,Arial,sans-serif;
}

Olá ~DarkCheats !

O código resultou ...
Obrigado !

Até mais !
