The name is a bit funny. For my online part, I use ObsidianPortal, which also uses Markdown, but I don't think has anything to do with Obsidian.
Yeah I know about ObsidianPortal and I understand the similar name can be a little confusing which is why I added the .md part at the end.
I tried ObsidianPortal a while back and found it wasn't to my liking.
