Hello.
I have came to a conclusion that there is needed statistic in modded CS servers. The /rank command shows only kills/deaths etc., but in, for example, Zombie Mod server there killing someone is not the priority. Then I would like to create some statistic plugin for ZM server. But I have no idea how to start coding it

I have made some little amxx plugins, so I'm not professional. But I have programming experience in other programming languages.
First, I would like to create, for example, how many players you're infected.
Any ideas how to do that?
