    format(string, sizeof(string), "%s says: %s", GetPlayerName(playerid, Name, sizeof(Name), text);

Very basic, simply creates a file if it doesn't exist, and when the person uses regular chat (not commands) he creates a log with the text he has in it. The name of the file is his name. I'm not even sure if this will work, I simply took this from another script and changed it to my liking.

If you want to make it so when someone uses a command, it adds that to the file, simply tell me and I can create a function that will do the above but also show what command was done.
