I’ve added a page that talks about formatting text within your comments on this site. People have been asking for this, and I finally got around to it. You can also view this page by clicking on the link right above where you are typing your comment, “For help with getting your commented formatted, click here.”. Clicking that will open a new tab or window, preserving any unfinished comment that you are typing.
If you have suggestions for other features that need to be talked about there, or better wording suggestions, we are definitely open to improvements!
