Trello accepts Markdown in card descriptions and it even helpfully links to the [Markdown syntax](http://daringfireball.net/projects/markdown/syntax) page.

That page mentions that *"for any markup that is not covered by Markdown’s syntax, you simply use HTML itself"*.

However, using `<del>` for example to strike through text does not result in satisfactory output. Neither does using some other HTML tags like `<strong>` or `<em>`.

Admittedly, `<strong>` or `<em>` really don't have to work because Markdown supports **bold** and *italic* formatting, however Markdown unfortunately lacks in `<del>` department, and probably in others too.

Is there a way to show that a text previously existed but now does not, in Trello, if strikethrough is not available?
