I've got a mini-update coming out for Approval Studio that adds in some optimization for the approval process and also adds a documentation section in the Settings area. I did this because it turns out if you do not have an SMTP system setup for your WordPress sites, any emails can be severely delayed or even never sent. So, by including a video and documentation on how to set up an SMTP connection for a WordPress site, it should solve most of the deliverability issues that some experience with Approval Studio.
If you want to "test" the beta-release of Approval Studio v1.1 prior to the official release on Monday, you can download the plugin directly here.
Part of the reason why I'm not releasing the plugin this evening is that I want to finish up some of the documentation for the plugin and push out the release at the same time the documentation is ready.
