We're waiting to hear an update on the fish extender situation, as well. I've already started preparing some of what we'll do with a group of about 25 staterooms in mind (although I could plus or minus a few)...so I really hope that's still the direction we're going!
The last time we did it and it was broken into groups, the organizer split people up into stateroom groups of 20-25 cabins each and people had the option to say if they'd like to be in more than one group (so that then they would be giving and receiving to a larger number of cabins). I suppose it's entirely possible that you could ask to be in EVERY group if you were that ambitious!
I think it was threebritts (or something close to that)...but she has not been active on this thread in a very very very long time (although I think I did meet her in passing on the repo/Alaska cruise this past April and May). We're getting much closer to our sail date and so I guess I'd suggest that if someone knows how to get in touch with her and ask her if she's still organizing and can give everyone an update, etc., that would be great....otherwise maybe someone else needs to volunteer to help organize it?
