clients have a hard time opening documents to sign. they get an error message or just can't open to sign. Sometimes it takes hours for them to receive a document. Clients also have a hard time printing out a form they signed

Kara was spectacular Kara was spectacular! I was having trouble merging 35 small PDFs into a single larger document. She walked me through all the steps, and I told her what I had done and where I had run into problems. When she could not find a solution for me that way, she offered to merge all the documents for me!!! I have been working on this family project for the last 12 months and this was the final step before I could get the finished document out to everyone. Now I can do that and put this phase of the project behind me! I salute you Kara!!!
