NOTICE / AVISO

 


As many of you may have noticed apart from the Ulozto problem the main Mega account has been suspended, therefore the blog will be temporarily down until we can restructure and normalise the blog. I appreciate all the support you have shown me. Thank you for your understanding.

Como muchos habrán notado aparte del problema de Ulozto la cuenta principal Mega ha sido suspendida, por consiguiente el blog se verá disminuido temporalmente hasta poder reestructurar y normalizar el blog. Agradezco todas las muestras de apoyo que me han brindado. Gracias por comprender.
