...It's more difficult for me to read and understand english that write program coding....
While it is apparent that English isn't your 1st language
, I think you are doing a remarkable job. Definitely better than I could ever do with French. That said, if you would be open to some constructive criticism, in a couple places your program says "... was create". The correct way to express the past tense of "create" in English is "created" so from an English point of view it would be more correct to say "...was created". Personally I could care less and wouldn't of even mentioned it if you hadn't brought up the English topic.
By the way, I think you have set a forum record of having more "helpfuls" than posts.
Keep up the great work!
