Somebody is either quitting or dyeing (is that how you spell it?). There should only be three, where did you see four?
DOH! Ida is correct. There are 4 board positions open for SCHOA So many boards, so little time. (Dying)
Here is what a google search has to say about the word. The first thing that you probably noticed when typing out dieing on your computer keyboard is that a red line appears underneath it. What’s the deal with that? Well, that’s because dieing is actually a misspelling. Yes, that’s right; dieing is a common misspelling when used to refer to death, but that doesn’t mean that it isn’t a word. Alhough Microsoft Word doesn’t recognize it, dieing is a real word, but it isn’t at all related to death. If you are dieing something, you are cutting or stamping it with a die, which is a device used for cutting, forming, or engraving metals. It is a process used in machining, and your local town may even have a “tool and die shop,” which would make extensive use of the process. With the exception of this specialized use, average writers will almost never find themselves using the verb dieing, so they can effectively eliminate it from their vocabulary. Just remember, dieing has nothing to do with death, so unless you’re talking about machinery, forget the words exists.
