It's great. My kids have a lot of form for school that we have to print, sign, and then scan back into the computer. This prevents them (or me) from having to do this, great software!

Love this tool. Very intuitive and well built webApp (UI and UX are great). For the UX though, it can be a bit tough to jump in and out of different modes (editing which is "Open" - maybe call is "Fill", and tough to get to the fillable edit section). I work in Analytics - let me know if there is a career at PDFfiller for me: https://www.linkedin.com/in/andrewmiller09/

I am using this service as an ex-pat in Ecuador to communicate with government services in the U.S. Not certain yet if offices like Social Security will accept forms mailed from an online-filler service, so am withholding the 5th star until I know they'll actually accept my forms.

EXCELLENT Customer Service I requested a refund on my annual subscription after it had been taken out of my account. I explained that I don't use the software, and did not need to have my subscription renewed. The person who helped me was very kind, and responded promptly. I had a full refund within 48 hours! EXCELLENT customer service!

What do you like best? Not much not to like. Spell checker would be nice. though. What do you dislike? After creating a document and saving it, it landed back in the template folder. Have to switch over to documents to access What problems is the product solving and how is that benefiting you? Editing PDF DOCs. Ability to search works great.

Have not been able to successfully append a document more than 5 pages. That process does not appear to be very user friendly to figure out. Would love some guidance on how to do specific things with this program now that I have purchased it for a year!

Add a one-time use subscription Add a one-time use subscription. I feel this will be beneficial to a lot of your potential customers that do not run a business and may be using this software for personal use. I feel like a one-time 48hr subscription that can be purchased at a low cost would be profitable, especially if it can be repurchased at a later date if the user needs to use the program again. It does not make sense to offer a free 30 trial to users who are not going to use the program for more than 48 hours. I used this for free and you could have made money off of my usage by providing a one-time use subscription. Now, I have to make a new account with a different email if I would like to use your program again because I cannot afford to pay $100.00 for a subscription that I may only use once a year. So, just a suggestion.

Push Element on Stack Once you have a Java Stack instance, you can push elements to the top of the Stack. The elements you push onto the Stack must be Java objects. Thus, you actually push objects to the Stack. You push elements onto a Java Stack using its push() method.
