    if(sscanf(params, "s", params)) return SendClientMessage(playerid,red,"You need to enter user nick");

    new file[128];
    format(file,sizeof(file),"cServer/kasutajad/%.ini",params); // edit  .ini to your extansion
    
    if(!dini_Exists(file)) return SendClientMessage(playerid,red,"That user does not exist");
    dini_IntSet(file,"AccountActivated", 1);//I guess these is right you dont need to edit it
    return 1;
}

I used zcmd+sscanf but you can edit it to whatever you want cos you know how is it works now
And i must note that these is just if player is not connected !
