public Action:HookPlayerChat(client, const String:command[], args)
{    
    if((client != 0) && IsClientInGame(client))
    {
        if(CheckCommandAccess(client, "" ,ADMFLAG_SLAY, true))
        {
            decl String:szText[256];
            szText[0] = '\0';
            
            GetCmdArg(1, szText, sizeof(szText));
            
            if (szText[0] == '/' || szText[0] == '\0')
            {
                return Plugin_Continue;
            }
            
            else
            {    
                if(GetClientTeam(client) == 1)
                {
                    PrintToChatAll("\x01\x0B\x01*SPEC* \x04[Admin] \x01%N : %s",client, szText);
                    return Plugin_Handled;
                }
                    
                else
                {
                    new String:name[50];
                    GetClientName(client, name, sizeof(name));
                
                    if(IsPlayerAlive(client))
                    {    
                        Format(szText, sizeof(szText), "\x01\x0B\x04[Admin] \x03%s : %s", name, szText);
                    }

                    }

                    {
                        if (IsClientInGame(i) && !IsFakeClient(i))
