Anyone who would like to check out the map my team has been working on since April 2010 can now find it on the US Battle.net by creating a custom game and searching for "Hotkey Trainer". It is single player, so no need to search for it on the join game screen.
It utilizes many features of the StarCraft 2 editor that remain unused by many maps out there, so even if you don't need Hotkey Training, it's worth a look. It's even got licensed custom music in case the plain SC2 music is starting to get a little old.
Please leave any comments or suggestions you may have!
