Hi - We are using a user level of "guest" on a Joomla 2.5.x site for the purposes of showing/hiding login and logout menu items. That all works fine. When I installed and configured your CMandrill extension, and enabled the Mandrill plug-in, I received an error message when tried to register a new user. It made me think the plug-in was not triggered since this menu item was set to "guest" and the access level for the plug-in was "public". I changed the access level for the plug-in to "guest" and tried the registration process again. Sure enough, it worked fine. When I went into the CMandrill dashboard, I see this message: "So, you've provided an api key! That is awesome! However it seems that the System - Mandrill plugin is not enabled. If you don't enable it, we won't be able to send mails through the Mandrill service! To go to the plugin manager and enable it click here." When I click the link I see that the plug-in is in fact enabled; however, because it has an access level of "guest" your code does not consider it enabled. This guest/public behavior is optional in Joomla 2.5.x, but I believe it is standard in (at least) Joomla 3.2+. Is this guest/public functionality supported in your code? If not, it appears I will need to make a change in the CMandrill code to work with Joomla 2.5.x. Thanks!
