Composr can be customized to disable member signup. This is used to prevent the guest users from joining the website. Site administrator has the provision to enable this feature. This is not a directly configurable option in Composr. Instead, administrators can deny access to the “:join” page in their site. This prevents the guest users from joining the site.

Follow these steps to disable signup feature in the website:

* Go to Admin Zone > Security > Permissions Tree Editor. (image_001.png)
* Select “Module: join” by expanding the “Zone: Welcome”. You can see a green circle next to “Module: join” since the list reflects Guests' permissions. You can change the display by changing the item in the dropdown menu highlighted in the image. (image_002.png)
* Then you can change the permission for each usergroup for the “:join” page in the box given. Use the “+/-” button to select/deselect all the check boxes.
Deselect all the check boxes to disable signup feature of the website. And press the “Set” button to save the changes. (image_003.png)
* Pressing the “Set” button will display a success message on the screen. (image_004.png)
* It will change the colour of the circle to red which displayed next to the “Module: join”, since no users can access the “:join” page now apart from website administrator. (image_005.png)
* We can check this feature by logging out and go to the URL:
<domain-name>/index.php?page=join
Now, the page will display an error message similar to the one in the given image.

* We can customize the error message displayed in the “:join” page by going to
Admin Zone > Security > Match-key page restrictions. (image_007.png)
* Enter the page name (“:join” in this example) in “Match-key” box and custom message in “Message” box under the “Match-key permission-denied messages” heading. Then press the “Save” button to apply changes.

* We can see this custom error message by logging out and go to the URL:
<domain-name>/index.php?page=join
Now, the page will display an error message similar to the one in the given image.
