There are plenty of tutorials on exporting and importing models as .m2 files, but I can't find anything on making new animations. Are there any guides available on how to work with them?

Option 1:You would need to animate in mdlvis and convert mdx to m2  with mdx to m2 lazy Not recommended because verts rig only 100% no blend weighting.
Option 2: buy highlords tool for converting gltf into m2, Note: Rigging takes quite a while depending on how many bones you use, but it is a good tool.
Option 3: Wait for skarns blender studio to be released, most recommended.
NOTE: If you want to prepair a model in blender for conversion when skarns tool comes out or for when you buy gltf to m2, please keep in mind that you can not have a parent a bone to a bone that has a higher id than it. so this means if you parent a bone. make sure the bone it is parented to was made before the bone you are parenting. 

ps. if you need help learning to animate with blender pm me.

Yeah vertex only animation is usable for very few things, always better to use bones. Making an important tool behind a paywall is terrible, not going to support that.

Guess I'll be waiting for Blender Studio, where I'll prep the model in 3DS Max then punt it into Blender. Has there been any ETA on Blender Studio?
