Thanks for the compliments! It's great to become an active member of the development team for the module and for comsite.org!
Since the initial release of this version we have had 3 small patches to the module code (all available on CodePlex) and updated the stable release packages for the module (being as this all has happened within 24 hours of the latest version release). Any downloads in the first 24 hours of the release may need to have the patches applied to regain functionality of the email notifications as there was a minor glitch. Any current and future downloads of the module now include those patches already applied. Sorry for the inconvenience!
Apparently we are experiencing a little trouble with our support forums currently, but this should hopefully be resolved soon as well. The module is available directly at CodePlex via http://simplyclassified.codeplex.com and the patches are available in Source Control as will for those who downloaded the module before this posting. If you encounter any further issues, be sure to raise a bug report on CodePlex so we may dive in and resolve these as well.
I will start on the roadmap for the v1.00.13 Public BETA release very soon and hope to have v1.00.14 Public STABLE out soon after! Thanks again for your support.
(sidenote to DNN.com admins - my apologies for the triple post last night - the forums responded to me with an error when I submitted the first two posts. On the third, I finally got the response that the post was awaiting moderation and would be available soon. You guys might want to look into that, as sometimes when you post here, the forums return an error even though the post is submitted and awaiting approval.)
