Concise description:
There should be a link to all Beta map's threads from the game page. I know that there is a link from the my my games, if you click on the map thumbnail, but then if you have 50+ games, and you've skipped 4 or 5 to play later, when you come back, you have to skip them again, whereas you could just left click to open in a new window and not worry about that.
Specifics/Details:
It would be for Beta maps only, link would be removed when map goes out of Beta
How this will benefit the site and/or other comments:
Well, this is bloody well what Beta maps are for, now isn't it? =D
