How to underline text, help..
Markdown doesn't have a specific underline tag.
If you really want an underline you could either hack it in via css or you can use the html <u> tag.
I think you can enable by: Settings --> Markdown --> Enable ++insert++ Option. Than you can underline text by ++text++.
Though technically it is not the same as underline <u>, at least it looks like the underline.
Thank You!!
