Your mileage may vary. In our situation, this very well thought out Plugin had inconsistent issues with:
- the NONCE checking routine
- the server email confirmations routines (not always sending confirmations)
- the Entries index Page in the Dashboard is not well thought out (it simply lists the same confirmation contacts, and not the User specific Form information that would allow sorting.
The issues may be related to our specific mail server (typical LAMP) set-up or Theme conflict, but the Plugin needs to mature more to work with those typical set-ups to be of use to us.
[We did pay the Pro fees, Support is minimalistic. We wanted to love this Plugin, it is sooo close, but not in our specific setup.]
