use the playdota.eu bot
What do you mean?
I followed these instructions:
Creating any other (custom map) game:
Step 1 - Join channel playdota.eu on server EuroBattle or FawkzBNET or RGC
Step 2 - Type /w playdota.eu .map <pattern> to load any map from this map list.
If the map is not in the list you can upload it from EpicWar via map upload page.
Step 3 - Type /w playdota.eu .gopub <game name> or .gopriv <game name> to create a game you loaded
Step 4 - Join the lobby and enjoy your game
