so far I like it, im just not sure the20/month is worth doing only 2 or 3 documents/month.....seems pricey to me. Maybe you should offer a per page fee.....at this point its costing me7-10.00 per page.......

I like that I can find most of the forms I need bit it is very difficult, at least for me to align some of my typing to the actual corresponding lines. (eg): pleading paper. Im sure there is a way but i haven't learned the whole program yet

A great move for my professional career, being able to fill out and sign forms digitally as a self-employed musician and house painter who has to do all the clerical work themselves is a huge advantage. Thank you for this great service.
