A friend of mine had worked on a text for Wikipedia. It was a great text and, I urged him to upload it. This did not happen. I tried to be polite and did not prod him aggressively. At some stage, it was almost a month later, I asked him about it.
His complaint was that it did not work. He had tried it many times only to find that the file was not one of those that could be uploaded. It finally dawned on me that my terminology was the problem; had I said that he had to copy and paste the article everything would have been fine.
