Well, we're into tech week and I would have to say the experiment with Google Sites was a 50/50 success -
It turned out to be an invaluable resource for the production team. Everyone used the site at least once, either to upload documents or download them, and having the calendar and contact lists online turned out to be beneficial. The producer for the show said he has plans to make this a permanent fixture for future teams on several more complicated shows coming up, specifically Rent and Annie.
Unfortunately it wasn't as successful on the cast's end. For the first half of rehearsals I only did the online callboard, which after it was updated would send an email to cast members. But several of them, even after reminding them twice to subscribe to site changes, did not subscribe; and after one time when they didn't get the callboard updates, I switched to personally emailing the callboard. I didn't want to take a chance of another missed rehearsal when we had just a month to rehearse. Every rehearsal was precious! Another problem I had was syncing Google Calendar with Sites; even when I had given an actor permission to view the calendar, Sites would say they weren't authorized to view it. The only solution I found was to make the calendar public rather than private. From the feedback I received I believe if this problem hadn't occured so early on and for so long the actors would have used Sites more.
Overall I'm really glad I tried it, even if it wasn't 100% successful. Were this another show with more rehearsal time, or a musical that would require more people in more than one rehearsal space, it may have gone differently. I'm glad that the end result meant that a theatre will be using Google Sites for their production teams and that I was able to introduce the process to them. I will definately be trying this again as soon as I am able.
Since we've abandoned the actors version for now, I am able to send invites for those that would like to view the site. PM me if you would like to take a look at it and I will add your email address to view it.
