So far it is my first day and it is pretty good

Anonymous Customer

I was desperately trying to edit a pdf copy of the P&S and we could not convert it to a Word document. Finding your website where I could make edits to the form, made my life a whole lot easier. However, I work for a law firm and we normally do not have to do these types of documents. So I am afraid I will have to cancel once the document is finalized. At least, I will keep your website as a place to go to if there is a future need. Could you please cancel my membership after the 30 days I already paid? Thank you.
