Thank you so much for the super prompt reply! I had somehow removed the date stamp from my digital signature and I could not figure out how to get it back on. Turns out it was a pretty simple fix (doh!). Kara responded super fast to my cry for help. She provided written instructions as well as a screenshot (very helpful!). My date stamp is back on. :)

I have used pdfFiller multiple times… I have used pdfFiller multiple times and love their product. I primarily use it when applying for jobs and need a pdf converter to fill out applications. I like that I can just subscribe for the time I need the program and then cancel it. I also like that all my documents are saved to my account even after I cancel the service. I can just resubscribe and pick up where I left off. Customer support is EXCELLENT. Highly recommend pdfFiller.
