Does what you want it to do...I purchased the first tier as I will never have 500 signatures in a year, let alone a month. A few limitations I have found. 1. Single user at this tier, that seems really light. 2. Only one link for the entire account.

The first one I can kind of understand...but the second, this is just silly. Why not have a link for each document? Why am I forced to 'email' the document through the system?

Overall, interface is nice, tool does what it should, but does have a few limitations.
