Yes, the Initiative would be willing to share the information with him! You've pretty much got it right there, they'd be able to give him numbers of transports, numbers of worlds accessed, how many from each, and that sort of taken character page info.

And in terms of characters no longer present, since we don't really have an OOC record of that, we'll tie it into the tag system. All characters under the generic 'dropped character' post were logged into the system before a fully comprehensive system had been created, so there's record of them but no real organization to it (IE it can be ICly dug through, but it would take some time).
Characters with the † in front of their name were logged in the system as soon as they accessed the tablet (thus characters that never tagged/posted are unregistered and not in the records), and it's as easy to access that kind of information ICly as it is OOCly, as long as you know where to look (and the Initiative would be happy to show him the system for it). They wouldn't outright give him, like, a spreadsheet of appearances/disappearances, but this system would have all that information in it available for the digging up.

Does that sound alright, and is there anything I missed in that?
