How about the following? (1) Identifying the exact version number of Atlas 2 to which you refer -- in your message and on the DigiArea web site? With my licensed copy of Atlas 2, in the Documentation Center page guide/InstalledAddOns, I see that I am running Atlas version 2.3.0. And the "Update" button in the "Manage" section for that item on the page is not highlighted, so _presumably_ I have the current version. (2) Providing an easy way to tell within Atlas what the version is. In fact, it should be a "law" for any commercial or free add-on: within the context of the add-on, include a variable that returns the version number. E.g.: $AtlasVersion or $Atlas`Version I tried some poking around in the Atlas add-on files themselves, but in Atlas.m I see: (* :Package Version: 2.0 *) (* :Copyright: Copyright 2011, DigiArea, Inc. *) (* :Mathematica Version: 8.0 *) So how am I supposed to tell easily what version is really there? Add-on providers, especially commercial ones, should be subject to 10 lashes from a wet spaghetti if they fail to include such a function.
