Thanks. I haven't had a chance to mess with yours yet, though I did download the multi-world version. The possibility of having several different ones available from the same script does have an appeal. At first glance, it looks like I could easily take one of those entries and tweak it for a custom calendar (or add another option). Of course, given my level of ignorance of this sort of thing, it probably won't be as simple as I think it might be.
