A THREAD FOR NEWCOMERS!

1. Where can I find champion streams and replays? I want to learn from the source of ancient wisdom and see how skilled players build their strategies, for example. Commentary during the game would be desirable but not necessary.

For example, here: http://heroes3.tv/ Follow the streams of Maretti, Stinger, and Gomunguls. In general, watch the broadcasts. Right now, Twaryna is playing; it's worth watching. And here you can watch his past broadcasts endlessly: http://ru.twitch.tv/twaryna/profile/pastBroadcasts

2. Is there a guide or dictionary of slang and terms used in Heroes somewhere?

There was something like that: this idiotic topic where everyone called units whatever they wanted, but this isn't really used in gaming slang. This makes its usefulness almost zero. There were also some good posts: 1 2 3 4, but they got lost among a bunch of nonsense.
