The bot does a great job of storing all of the information it needs.  If the Director passes it your username and server, it can automatically remember the rest of the information and fill it in on the login screen.  This is a great security boost, not having all of your passwords stored in the config file.  

If you really want to put your password somewhere, though, there is a User Notes field that can be used for anything you want.  Some people put their alliance name or password or account type (main, feeder, etc) in there.

The Director has macros built into it. Macros are string replacement keywords.  These macros allow you to type a short predefined keyword into the bot and the Director will replace it with some other text. Several simplified and handy scripts are already available to you with The Director macros.

For instance, if you type:

useamulet

The Director will replace the text "useamulet" with this:

Type:

mechattack

and it will give you this:

attack %coords% %attackheroes% cp:45k,b:45k,r:5k,a:500,wo:500,w:500,p:500,sw:500,c:500,cata:500,t:500 %landingtime%

There is a list of possible macros on the Help menu in the Director.
