osDate Admins
osDate has two levels of admin: "super" admin and regular admin. The regular admins can be thought of as moderators - they have only those permissions allocated them by a super admin.
When you install osDate for the first time, there is an "Admin Password" field. This is the super admin password. By default, the admin login is "admin", and the super admin password is "pass", but you're encouraged to change this after login.

To access the admin interface, go to http://www.your_domain.com/admin/, assuming osDate is installed in your root web directory.
You will be presented with an interface similar to this, although it may different depending on your osDate version.

The password is the one specified during installation, or just "pass" if no admin password was specified.
To create a new admin which is not a "super" admin - i.e., a user who will have partial access to the admin tools, click on the Admin Management link on the left column, at the top.

Click on "Add Admin" at the top of this screen, and input the username and password for this new admin. However, do not make this a "Super User", or the admin will have full access to all of the admin tools. Be sure that "Enabled" is set to "Yes". Here's the result that I had after these steps. Your "Id" value may be different from mine, but that isn't something that you should be concerned with.

Now, click on "Admin Permissions". You will observe that only non-Super User admins are listed. This is because super users have default access to every tool. Depending on the version of osDate that you are using, your list of "modules" may be different, or in a different order, from those shown below. Also, please note that these are not modules in the sense that they can be un-installed. "modules" here means simple "parts of the system that you can restrict access to".
Now, logout and login again using the new admin login. You should see a restricted toolset in the left-hand column.
