Mi nombre es y soy un adicto a los foros. :oops:He estado fuera del camino durante varios años e incontables veces he intentado parar pero es inútil... Necesito alimentar mi adicción al aprendizaje... :!:
Ahora un poco sobre mí... Soy un tipo bastante reservado en términos de privacidad en la red... especialmente cuando las cosas que escribes son visibles para cualquiera con una conexión a la red. Pero me encanta compartir la información y el conocimiento que tengo, así que por eso estoy aquí, para compartir y aprender.Comment
