I hate handwriting forms. This is such a great alternative. I have been filing out piles of documents for an international adoption. They are neat and easy to read.

Decent, though the affiliated linked program options which supposedly come with the upgrade purchase don't seem to work / or be actually as advertised.

It's essential for digital nomads It's essential for digital nomads. Since my base is in the US. I rely on these solutions to continue operations in the US from abroad. I would integrate payment systems, especially with the banking networks to be able to send money orders or checks physically. And I would suggest connecting with virtual offices to be able to interact with clients in a virtual office setting. I'm thinking a virtual secretary solution... just some thoughts to improve. Abe

Useful for filling out applications. Its been so useful for applications that I'd otherwise have to write by hand. I have arthritis and writing information in tiny spaces is painful and there's never enough room for the answer. This has solved this problem.
