I've only done two documents, but so far I think it is a swell program! I have one more trustee that I'd like to add, will that cost more? We use the program for a charitable trust and we are unpaid. Thanks a lot, no matter what the answer is! I really like the program. MP

By my own ineptitude I was having trouble printing a document. I thought I had to upgrade and then found out I didn't have to. So I reached out to get a refund and keep my original subscription and got that refund in MINUTES! I am a VERY happy, satisfied subscriber! And, I'm getting better at it :)
