admin doc: clarified the instructions a little more

...it seems some admins are, well, not quite ready to be admins :)

(also some minor typo fixes slipped in)

 ### administer
 
   * ask each user who will get access to send you a public key.  See other
     sources (for example

     for how to do this
-  * for each "user" in `$GL_CONF`, copy their public key to a file called
-    "user.pub" in `$GL_KEYDIR`.  For example, mine would be called
-    "sitaram.pub"
-  * edit the config file (`$GL_CONF`) to add the new users in whatever way you
-    like
+  * rename each public key according to the user's name, with a `.pub`
+    extension, like `sitaram.pub` or `john-smith.pub`.  You can also use
+    periods and underscores
+  * copy all these `*.pub` files to `$GL_KEYDIR`
+  * edit the config file (`$GL_CONF`) and give the new users permissions as
+    required.  The users names should be exactly the same as their keyfile
+    names, but without the `.pub` extension
   * backup your `~/.ssh/authorized_keys` file if you feel nervous :-)
   * cd to `$GL_ADMINDIR` and run `src/gl-compile-conf`

+As a developer, I send a file called `id_rsa.pub` to the gitolite admin.  He
 would rename it to "sitaram.pub" and put it in the key directory.  Then he'd
 add "sitaram" to the config file for the repos which I have access to.
