I don't know if you've noticed the scrolling banner at the top of the forum here, but there is interest in doing a Tokyo Underground manga scanlation project. I don't know if the current team wants to be involved in that or not or whether there's been any progress in finding the personnel for doing that as yet, but it's an idea worth pursuing!
I can't fully speak for the project team, but I think there may be a possibility that the team will go ahead and do Volume 39 as well, partly because (as I understand it) the person who did it previously does not plan on distributing it publicly for online reading. Our team shares the chapters after a week's wait with online reading sites, so if there was no Volume 39, I think there'd be a GB fan mutiny or something.
I guess we'll see when we get to the end of the current Volume.
Even if there were no other projects in the offing, I'd like to think that this forum would remain and that we'd be able to participate in GB discussions!
