If in List titles you like to create numbered text like this:
3. Something
Write it this way (to escape dot), so it shows correctly:
3\. Something
Wekan uses GFM (Github Flavored Markdown). We use the following project that ports GFM to meteor: https://github.com/wekan/markdown with updated newest markdown, that is fork of https://github.com/perak/markdown.
Newest Wekan uses newest markdown.
