http://foros.3dgames.com.ar/warcraft-3.42You may be able to comunicate with the ombuserver staff in here, I hope so.
This forums are of spanish talking people but im sure that if you post in english, you will be able to communicate too as many people speak english too.
I hope something may be able to be arranged.
I think that people with playdota.eu bots in latin america wouldn't have such a bad ping that they couldn't play. On eurobattle.net i've personally play using this bots and there aren't such high pings so that no one could play. I've also play with people very far away and we were able to play too without enormusly high ping.
I do think that this bots will be very usefull in the ombuserver and that many people would use them.
