Not too sure about hotkeys, already get tons of messages about people accidentally all inning due to hitting max by accident etc.
Also we now have a subreddit, will keep it updated. I'm not too sure about the forum's stance on giveaways etc at the moment so we'd likely do giveaways through reddit as well. Feel free to subscribe:
http://www.reddit.com/r/Primedice/Bitcoin giveaways are fine and are still allowed in the games and rounds forum. It's just alt coin giveaways that are now banned.
