Take your time. It can be a bit overwhelming at first. The NM.io front-end is basically a clone of Steemit, so if you're familiar with that you'll be fine. LOTUS is a reward token that NM uses which is connected to steem and awarded in the same way. These tokens can be seen and exchanged on steem-engine.com. That's something I still only just understand well enough to use, but not much more than that. 😆
