I’ve been writing a form letter in LaTeX with WikiBooks’ guide. To my dismay, the default formatting yields a huge top margin.
Fortunately, Eliezer Kanal at Shady Acres has found the fix in the \opening section within letters.cls. All I had to do was manually \setlength the \topmargin above the printing and the \textheight of the main text box, and it formats correctly.
Happfully Ever After
