are there any group doing the subs for the movie or planning to?
"In regards to next week: there will be a special broadcast. A preview (22 min preview, that is) of the Index movie will be shown instead of a new Railgun episode. Seeing as how we’re already doing the movie, and that it’s coming out in late August, we will not be subbing the special next week. Please don’t expect a change of heart, as it’d be useless to waste our Friday subbing a movie we’re already releasing at a later date."
