How to change the pop-up messages
From HAA Best Practices Wiki
The messages that pop up when you first access the site are controlled by Nova Sticky Messages. The simplest way to modify them (or turn them off) is to go to:
Joomla->Extensions->Module Manager
and then click on Nova Sticky Messages (or perhaps Pro Sticky Messages, depending on when your site was established).
To turn the notes off entirely, select "Unpublished" in the Status drop-down list.
You can edit the messages for Guests and Classmates in the boxes on the right-hand side of the page.
If you want the initial messages to only appear once, set "One time cookie" in "Basic Options" to "Yes".
The module has lots of additional capabilities, including sound, video and links, which we have not explored.
