numberz wroteYes, but how?
I don't have the AwareIM Config Tool available right now, but you first need to do as ACDC said, set a CSS class on your menu item.
For instance, you can write the word green
Go to your AwareIM install location on your server and go to this folder: AwareIM\Tomcat\webapps\AwareIM\Custom\CSS
Create a folder with the same name as your AwareIM application.
Enter the folder.
Create a file named style.css
Write the following:
.green{background-color:#00ff00;}
You should watch the official instruction video here: Using CSS and Javascript in Aware IM
It has a more detailed instruction.
