Hello!
How many instances can I install on 512Mb RAM digitalocean droplet?
It depends on your setup, and community size. One of the biggest factors is if you're using Redis or MongoDB as a data store

One at least
If you'll use Redis, and your forums will have less than 100k messages each, probably two
If you'll use Mongo, in the same circumstances, maybe even three instances
However, I'd recommend you to use 512MB droplet for each instance
Thanks, guys! 
(I thought, by default NodeBB will send me notifications on replies. I've noticed them only when accessed the site...)

From what little I've read so far, it sounds like MongoDB is just better. Is there any reason why people would use Redis instead? Is it easier? More practical in some way? Thanks!
@zg We just started on Redis, that's all. This forum was converted to MongoDB awhile back, but we support both at this point in time.
@julian - So, you recommend to use MongoDB, correct?
If yes, can you please share what factors made this choice?
More storage for posts in return for a small (negligible) sacrifice in speed.
