This may be a silly question, but I recently inherited a DotNetNuke site.  Looking in the settings, I can see it's running version 4.09.00 of DNN. Looking at current DNN 5.0 information, there appears to be several editions available (Community, Professional, Enterprise, etc).So my question is:Were these editions also available in the 4.0 version of DNN?If so, is there a way to tell which edition the site is running?  I didn't see any immediately obvious designation in the admin areas.Thanks!
How to know which edition a DotNetNuke site is

From the DotNetNuke Wikipedia page:The DotNetNuke Professional Edition was introduced in February 2009 with version 5.0. The DotNetNuke Elite Edition was released in September 2009.At least these editions were not available in version 4.
