Hi @digorsink! So while the Markdown for underlining isn’t supported, the HTML for underlining is supported on Write.as. All you have to do is add this to whatever text you want to underline:
<u>This text is underlined.</u>
Thanks for bringing this up though. This definitely relates to the question about extended Markdown syntax that has come up here before. If there’s something you want to do that cannot be done in Markdown (like underlining or adding color to text), just know that Write.as also supports HTML. You can use this guide to see what HTML can be used:
Hope that helps!
