The other day I added Get Smart, Bewitched, Hogan's Heroes, Gilligan's Island, and Mission Impossible to the spreadsheet where I track the chronologies of my fanfiction crossovers. Today I added Barney Miller (and by implication Fish). I want to add Mary Tyler Moore (Rhoda, Phyllis, Lou Grant), but there'd be too much overlap with chronologies already in the grid. Unless I added a row or a column. But the grid's been 3x3 for fifteen years...

I've also decided I need to count Dimensions in Time as Doctor Who Season 1993, the way I count the movie as Season 1996, so by my accounting the season that just concluded is the thirty-fourth. See, this is why I always refer to seasons by calendar year instead of by count.

Edit I've sorted my spreadsheet problems. The grid will still appear to be 3x3 for now, but some of the formulae I want would be too complex for a single cell so there'll be links to hidden cells.
