You can use it for your server
You can edit it
You can upload at another website, say MikuAuahDark made it
You can't say this is yours
You can't upload on another website without put me on credits
Notes
1. it doesn't use any library function(for stream files) for lua. it uses default io.open file:read function
2. if you want to learn how the code works, take a look at rank_desc.txt
3. there's a addional index which retrieves very first used player name on the server. Check rank.txt for more info

Version History
V1.4
Int function isn't global variable anymore
Rewrite code from stratch. It now ~10x faster than V1.3
V1.3
You can't read the first USGN that enter your server
V1.2
The file now is opened with binary mode which would solve a error that would not read the file correctly
V1.1
Player rank on server. I just accidently put "step" variable as rank number
V1.0
Initial Release
Another MikuAuahDark Scripts
Timer Extra function(timerEx) v4.0 (12)
Env_Laser v1.0 (7)
Weapon Hudtxt v1.0 (7)
Improved Badwords v2.0 (5)
