I would like to attend a webinar at some time, but for next few months I am far to busy to take time and energy for the webinar. I'm sure there is much to learn although I did succeed in working on document that needed to be done. This is a great tool; I look forward to continuing to use it. Thank you!

Just got the PDFfiler installed and it was easy to work and save. So far have a problem with printing or faxing the document to court. I have not learned all the works to the program yet, I'm sure that the reason.

I really liked the variable size eraser. I needed to send my bank statement out and I did not feel the party needed to know my balance when they were only looking for a particular debit.
