Problem #1: I cannot seem to create a crossword with more than 18 answers. I wanted to create a puzzle with 24 and I could not get it to work. Is there any way to increase the size of the puzzle?

Problem #2: After attempting to create a good looking puzzle a few times (with little success) the system stopped letting me create a new crossword. If I login as a new user I can create one, but only one. How can I change these limits?
