You will need to create an event plugin. You can achieve desired processing by fetching the "u_logout" event in your plugin.
Implementation procedure:
1. Create new page
Go to "Admin" > "Pages" > "Add Page".
Example of settings:
- Name of page: "Logout message"
- Position: "No link"
- Visible for: "Anybody"
- Heading to display at top of page: "Thank you!"
- Content: Enter arbitrary HTML codes
2. Create event plugin.
2.1 Create "my-event-handler" folder under qa-plugin/.
2.2 Make plugin files under my-event-handler folder.

3. Settings
- Go to "Admin" > "Plugins" > "My Event Handler" > "Settings"
- Set "Redirect path" option. It is OK either relative or absolute URL.
Note
Redirected page does not have to be pages in Q2A. It is OK at other sites (domains).
