ICM has gone to ground, I hope he surfaces again. I think he was busy paying the bills.
The donut tutorial is a great place to start. It’ll get you orientated with the Blender workflow which is quite a bit different to C4D’s. Once you get your feet under the table feel and everything feels less new you’ll discover an application that is incredibly powerful and a whole lot of fun too.
I have a huge list of great Blender Channels on YT if you’re interested.
Also here’s the Blender Community site, https://blender.community/c/
BTW, On Mondays is Blender Today live broadcast of development updates and questions from the community. Lots of really good info usually.
Graphicall is where to get early builds of experimental branches and special builds of Blender like Bone Studio. It’s also the best place to get the latest Animation Nodes Addon.
Some great Addons to look at on Blendermarket.com are HardOps and Boxcutter, MeshMachine and DecalMachine and KitOps.
Free Addons such as Sverchok and Sorcar node based procedural modelling.
There’s so much to discover.
