Trying this service for the first time. I needed the service to prepare a contract to buy real estate and wanted a slick presentation. It was easy to use.

I am not very computer literate although the system is simple enough to work with that I can do everything so far. I need to edit a scanned document and this is more challenging any help would be appreciated.

It was very good. However, I would be interested in the webinar because I have not figured out how to download a document from another site to my account as I was advised by the support person.

Easy to use!
I found the system very easy to use and have only scratched the surface. Converting documents to an editable form was easy to do and the system made it easy to find available PDF or other formatted versions online.
Saving different versions or templates was a bit of a challenge but that was easily remedied.

Perfect for my needs!
I found it super easy to use - was looking for a product like this and it really met my needs! I have used it for basic tasks and it works great.
I feel like if I ever want to do more creative documents that I will need more training. This feature is a bit complicated to me.
