naturally the feature would be only available for the SB members. But as you said yourself, since the stuff is allready downloadable by itself, there isen't actually that big need for such feature at all, but making one would mean work and that work, as outscored now, costs, and those cost would need to be covered.
Eh, It's only really possible because I took the time and effort to both scrape the board, and the current system offers read-only access to the file structure where everything is stored. Personally, I'd like the feature so that I can go and have an offline/local copy of everything for my own purposes.
By the way, figure an ETA of 0100 to 0200Z for the completed update for the board.
