1) if it is a time choice between making a post on a forum or writing an email that pushes a product further along, or finalising a contract, or writing a section of a book, etc., I always have to choose the latter. I learned long ago when writing Mentalism Companion that I could either stay involved in the Silent Tower mailing list discussions or write the book. Fortunately with Colin, Thom, John, and other authors & editors pitching in, you probably won't even miss me!
2) I normally expect 50% of all freelance projects to fail to reach a handed-in manuscript. Real life has a tendency to derail even the best-intended folks.
3) John has covered that one.
4) I probably will be in Indianapolis next year for the day job, all being well. Unfortunately there's a huge gap between the dates of M&M 2013 and GenCon Indy 2013. I will doubtless have to be content with trying to get to Dragonmeet and UK Games Expo.
5) the second unified Rolemaster manuscript escaped Gamma overnight, so one more to come and then I'll hand the trio over for some modest layout.
Best wishes,
Nicholas
