Better Resources for Learning Draftsight Needed

Does anyone know if there are in-depth learning resources for Draftsight like there is for Autocad. I'm referring to either books or video tutorials comparable to George Omura or Ellen Finklestein. I am a board trained architect of thirty years and am now switching to cad. I've been using the free version of Draftsight 2018 for about a month now and have gotten pretty familiar with being able to enter geometry. After a lot of hit or miss or bits and pieces here and there it's slowly coming together but what I would prefer is something more structured so that it won't take so long to learn. Thank-you in advance for any help you can provide.
