Hi. I'm also a beginner puzzle constructor. I have a puzzle I think is ready to go except for a concern I have over the answer, GERDAS. I have tried several times to change this answer but seem to be stuck with the G-E-R-D for sure. I wanted to use it with the clue, "Hitler's secretary, Christian, and others". I didn't know if Hitler was a forbidden reference for a crossword puzzle -- sort of like a disease. Any thoughts? Thanks.
