@fantin, you might want to quote your sources, as the vote from @cheetah links to a website that a large portion of your post comes from.
Cutting and pasting is not against the rules but you can get flagged if you copy and paste without quoting sources.
Hi my dear, how are you? I put it together with the calculator link. But I edited more clearly, okay? Search for "article credit source". Thanks for the warning, big hug XD
