So far... your chat feature to get support is great. I seem to be moving along just fine. I uploaded a document and completed areas of "fillable" information. I only did 4 STARS as I have not published this to my site and tested the form.

easiest way to fill forms! I like it and I recommend it to anyone who works with Forms that cannot be edited using another softwares. In my job we need to complete a LOT of forms (we are a law firm specialized in tax and corporate law so we need to complete a lot of forms that come in PDF format) and some of them doesn´t allow us to make any edit in the regular PDF program so PDFFiller is our salvation. It is super easy to use and it allows you to edit the entire document using only this software. You can add text or even delete parts that you don´t need. It is a software that doesn´t require any effort to understand because everything is as simple as upload the document, make the changes and save as pdf or print the document. I use it every day and I find it very complete for the things that I need. You are not able to use it in several computers, so if by mistake you open your session on another computer you may loose your work.

I am having some difficulties with the…formatting and printing I am having some difficulties with the form printing properly. The formatting does not transfer for printing to landscape and thus loses portions of text contained within the form.
