Hi!
Yes you are allowed to distribute it as long as credit is given :)
These characters look great btw!
Thank you!
I would add extra characters if I had time, but if you want to, you can import the fonts into BitFontMaker2 and create them yourself. It's a very basic and simple to use app, so it shouldn't be too difficult.
Hi! I would assume it works with rented servers, although I can't say for sure as I haven't tried it before and I don't have any experience with them. As for handling ~1000 players, I don't think I would recommend it. ZNet is more directed towards beginners and for smaller projects. It wasn't intended to deal with large player counts.
