I'm planning to write a AMXX plugin that let's CS Player register with their player name and password on my website, and ppl who want to use the player name in my server have to provide a correct password. Players who registed in website can have their own ranks.
I don't want to use steam-ID to identify players, because a lot of players are using no-steam CS.
Part of website I will write it in PHP.
And I m thinking about .... it should be used on single server, or I create a "united ranking" system, both of them which is better
Any other suggestions
