Just getting started with some of the applications, but so far, so good. Definitely beneficial in replacing lost forms. Looking forward to other uses. Maybe survey another time. Thank you.
cant get page to print. it says its been sent to printer, but doesn't print. Thought it could be my printer, but I checked it and it works fine. had to fax page to myself to get it to print.
It took a while to begin to understand how this works. I would definitely like to attend a webinar to learn more about it.
After I fill in all these forms I send you, how do I save them to my computer?
Thanks,

Using this site to fill out divorce paperwork. Sometimes the text is too big for the field I'm in, but other than that I think that the site is awesome.
Maybe I haven't found it, but it would help if there was a way to stop the fillable areas from snapping to each other. I had to figure out work-arounds for a lot of them.
