editing document is fine. Underlining is hard to figure out. Simply saving for future use (not exporting) is not clear but I stumbled on a solution that I hope will work.

I love it for the most part. Just wish I could send a document to a person without knowing their email (ex. directly to their Facebook account) with the ability to view and sign not edit the document. Other than that, it's been great!

Outstanding Online Support I have used Pdffiller for the past 4 years to file tax returns for an investment group with over 40 members. I made an error when creating my template and when I went to print the 40 documents an erroneous number was appearing, the result of my error in creating the document. Fortunately Pdffiller has an online support staff. So many online companies require you to submit a ticket and then promise a 24 to 48 hour response time. Pdffiller offers that option but they have an outstanding online chat support. I had the benefit of working with Ryan and got access to him immediately upon opening up the online chat support. This was in the evening but Ryan thoroughly researched and tested my issue. Sadly the only option that appeared to be the answer was to create a new set of 40 documents which Ryan was willing to teach me how to create the docs in way that would avoid this error. When I expressed my issue with not having another 6 hours to re-create my work, Ryan persisted in finding a work around that was very creative and saved me from over six hours of new work!!! Needless to say I was ecstatic!!! Thank you Pdffiller for not only a great product but an online support staff that truly cares about helping customers get the results they require!!
