On your client's website there's an Activities section. Your client wants to make it clear this section is not about activities organized by other art societies—it's only about SRUP. Could you please change the name of the section to SRUP Activities? It's a breeze.
1. Navigate to Content | Section Manager and click on the title of the Activities section to open it for editing.
2. In the Section: [Edit] screen, change the Title to SRUP Activities.
3. In the Alias: field, remove the existing alias (remember, the Alias is Joomla!'s internal name for the article used when creating user-friendly URLs). Leave this box blank; Joomla! will fill it with srup-activities when you apply or save your changes. You can check that now by clicking on Apply. You'll notice the Alias box is filled out automatically.
4. Click on Save.
