Good lesson to know; although, I'd rather find another PDF form filler that doesn't want to keep adding logos to the PDFs. If you mention this to a library patron, you kind of have to point out that they will only be able to fill out 2 non-editable PDF forms for free at PDFescape. After that they will have to buy some credits with real money.
I'm looking forward to the next lesson. Maybe Topia will be completely free and not add logsos.
