To start with I struggled a little bit and thought it wasn't working. However, five minutes into it I was already achieving what I wanted from the editing futures of this program. Many thanks.

Wow, I am just testing the functionality of this system. If it does what I think it can its like having a personal secretary/ administrative assistant. I will gladly pay the premium for the service. My one concern, I want to make sure the is confidentiality and protection for the documents I'm transmitting as they are confidential. These days identity theft and misuse of personal protected inforamtion is critical so, you're assurances my site is secure and my documents I choose to fax and mail from PDF filer are not being inappropriately accessed by PDF filler employees is good to share. I like the email code you require for me to log in, that gives me security. I would like to know that when "chatting" with your team, they can't see my actual documents, just my account. I have no reason not to believe your site is secure, but just sharing. I am considering purchasing a small business, I would use your service daily and would like to be able to "buy up" credits for additional fax capabiltiy. Great service ! I've already referred your system to at least 4 different companies including the mortgage company I'm working with on the purchase of my business who has stated they will refer their clients to it. Thank you.
