Hi Skymoon, I'd like to give my opinions on your post.
First offIt's not neccessary to write "would like to say thank you for", just "would like to thank you for..." so u can save time, space, energy... hehehe, and second, RESULT is an intransitive verb and phrasal verb "RESULT IN" is a transitive one. so the verb RESULT cannot be used in passive voice. moreover, Your contribution HAS not HAVE. :d:d
