i still don't see your point. i mean, out of the words you have highlighted maybe you consider contractions as a mistake which, are not. contractions might be considered informal language but not mistakes.

besides, what's wrong about using the word Skype?

well, anyways, all this issue you brought about out of the blue was sorta funny. thanks for the moment buddy :D

actually @sarasi proofreading was much more effective and straight to the point, thanks @sarasi. that was relevant.

Skype and Gadu-Gadu were drafted in as an alternative form of teaching here in Poland. The schools are highly competitive and are looking for varied and unique delivery. Only 1 school really went in for it and word has it that the idea fell flat on its face. It just needs to be implemented correctly
