Venho informar-vos que em breve irei desactivar o presente blog. Aquilo que nasceu de uma brincadeira, para comemorar o Campeonato Nacional dos juniores, tornou-se, num veículo de informação do nosso Clube.

Todavia, o CDPA merece um projecto melhor, mais completo, e actualizado com maior frequência.

Uma última palavra para os vários redactores, que aqui actualizavam a Vossa informação: obrigado.
