Finished the last read-over, glommed all the separate PDF files together into one HUGE PDF file, and uploaded onto CreateSpace! (Well, still waiting to get cleared there, but Whoooooooo! anyway!)
ETA: Man, the tiniest thing came up--the 5s in the font I use for page numbers stick juuuuust above the other numbers and into The Forbidden Zone. I'll have to move all the page numbers down juuuuust a smidge. Oh well!
