I like erasure feature in biz version. I find your index very hard to use. Where (what tab; how do I get there) is you general index of library contents and categories?

Easy to use Easy to use. Only one downside - can't bring in any other types of fonts. That would be helpful. Other than that it's good for my needs.

Everything is working I checked out their pdf software, it's truly great, I liked it and I was ready to buy a year subscription, but all these bad reviews on line about this company made me nervous. However I signed up and now I am pleased to work with it

One of the best customer service I’ve… One of the best customer service I’ve ever experienced !! My account had a monthly subscription which I thought I cancelled after the free trial but it didn’t seem to work. So I wrote them an email and within minutes they responded and took care of my issue and instantly refunded me the payments for the last 2 months in which my account has been subscribed. I’ve dealt with a lot of customer services over the past year and none has been so quick in responses, friendly and efficient in the same time. If I need a pdf service again, I’ll surely go to them. Thanks a lot & Best wishes Chris
