Well, you can't join to German team. (it's knew already :) )
The bots automatically connect to German team. 
         - (default is 12, change in: zzz_humansvsbots.iwd/maps/mp/gametypes/tdm.gsc --> at the bottom
         - add more: 
                     wait 1.5;
	             thread maps\mp\mbot\_mbot::addlotd();

              or ingame in console /rcon addbot axis 

       - In-Game mapchange DON'T WORK! (server downed, mod is bugged)
           if you will changing map, go to server.cfg, search example: map mp_toujane and change to map mp_carentan etc...
       - Change map every 3-4000 score, or server is downed with: "G_Spawn no free entites" (it's no serverhosting error)
       - if you have a modern webadmin, added timelimit, i think, 2-3 hours, and do the server restart. (ingame dont work)
       - Added 3 large map (mtl_bismarck, mtl_pirates_day, mp_karkand)
            if you use large map, server online over 7-9 hours. (night, or when you not online)
       - if you online a lot of time, use stock maps (server online over 2-4 hours). Again, RUSSIAN MAPS DON'T WORK YET!
       - low slots, few bots (server slots 12, bots 6) = server online over 1 day. (and server is full)
       - high slots, many bots (server slots 40, bots 20) = server online maybe 1-3 hours. (and server is full)

      IMPORTANT: Number of bots is higher, then "real" number of humans. (fx.: 40 slots, 16 bots, 24 player DONT WORK)
                                                                     but: 40 slots, 20 or more bots, = or less player WORK

       - use only server.cfg and coop.cfg (if you are better, change it :) )
       - maybe, i can fix all errors in the next version.

   Server options:

       - Enable Pure                 (sv_pure 1)

       - Disable PunkBuster          (sv_punkbuster 0)
       - Disable KillCam             (scr_killcam 0)
       - Disable FriendlyFire        (scr_friendlyfire 0)
       - Disable TeamBalance         (scr_teambalance 0) !!! IMPORTANT


                                                                       RUSSIAN MAPS DON'T WORK YET!

Thanks, if you read this, and you use my mod.
