I agree completely with dd4vols regarding letters. I copied the standard letters from PS into WordPad, make my changes, then copy back into PS for each type of return(1040, 1041, etc.) I shared them years ago, too.

Once you do that, you can copy the PS Common folder from year to year and get the letter changes from last year into this year's software.

I want to use my letterhead, not PS'. I want to have my signature JPG on the Organizer's letters. I have standard paragraphs like "Bank Account Verification" and I have Page Breaks set up between Instructions for Filing and Estimate Pages(if needed). All Standard now.

I wrote Philadelphia City letters years ago(!) and PS's City letters still stink! 

It's very easy to double click on another paragraph and insert it into your letters.
