Works without problem. Simple configuration.

Doesn't work
I installed the plugin and when trying to create my first popup I got the following error: “We could not load the editor because the defined template is no longer available.” I can't create any popups. Very disappointing, I really wanted to try this.

I like it.
I was looking for something lightweight, simple, and, with an intuitive real-time interface for my client. This met the requirements. Here are some sugestions for improvement, though. Adding a template with a picture and button. Now, the only templates with pictures are the ones with sign-up forms. Adding an option to set a lifetime of a cookie when the modal window is closed, including a session cookie for example. Adding an option to open a link assigned to a button in a new window. Don't load styles when no window is active. It can be simply done by checking whether any post of hollerbox type is published.

Spamming!
I was hoping that this plugin was good... Luckily I only installed it on my staging page. That page got permanently spammed by a message that says "Attention: It looks like MailHawk is installed but is not connected to the MailHawk service." I don't have Mail Hawk and I don't want it. But this message appears on top of all my sites in the admin area now, even after deleting the holler box plugin. Thankfully I can just renew my staging page and the spamming is over. But that's real shady business!

stopped working randomly on 10 sites
Garbage plugin, installed on 10 websites, after an update all popups stopped working. When I try to edit it says "We could not load the editor because the defined template is no longer available."

Buggy!
No. The software was riddled with bugs and modal popups that would display when the code threw an error. Really amateurish. I got a refund.
