We support Mardkown from <https://easyeda.com/bbs_view_297.htm>. All old topics' format are lost.

Oh. I find out why you report this bug. Because our Url has lots of '_' , so we remove '_' , just allow '*' and '**'. Check <https://easyeda.com/cms_files_how-to-use-easyeda.htm> . We are try to find a way to improve this.

Um, sorry, I don’t understand “**our URL** has lots of ‘_’ “, it was working with double underline for many days, until last week (or so). When I check with your linked “Markdown editor and viewer” the __double underscores__ work ...

Our URL is `https://easyeda.com/bbs_view_657.htm` , If the user just put the URL in the textArea, It will be https://easyeda.com/bbs*view*657.htm . I think remove `_` support is not good. Maybe we will add `_` later. >it was working with double underline for many days, until last week (or so). :), Yes We just remove that last week.
