In know this is only a $23 product but the support isn't all that great. Last time I heard from Paul was 2 weeks ago when he apologized for taking a while to get back to me and asked me to remind him of the issue.
I've sent 3 responses with links, images and other details, also offering to pay to get this working on our site since what we need is to have one of the fields set as optional. This is not a setting allowed in the plugin.
We've spent a lot of time changing auto-responder services so we would have one that works with this plugin because we believe it will increase optins.
Don't want to have the plugin modified by someone else since each update it would require additional custom modification to keep it working.
To be fair, this is probably just one guy and we all get busy or have personal issues from time to time. However, I did notice though that someone else rated his support as excellent 3 days age. I felt the same way the first time he got back to me, even though the information provided turned out to be incomplete.
Still, this is a great concept for an opt-in plugin and I'd really like to be able to use for our site without having to change our practices to fit one single plugin.
