You can allow unregistered users to submit applications. It can be useful if you need to provide the users an easy submission without registering on the site and finally save their time. Captcha is implemented to prevent spam and automatic submissions. You need to enable and configure core Captcha Joomla plugin. Also you have to select a user whom guest submissions will be assigned to. Lets set it up step by step.
Proceed to Site Administrator > Components > NorrCompetition > Options and click on Permissions tab. In the left sidebar click on Public tab or Guest tab to access permissions related to unregistered users. Have a look at the following permissions rules:
These rules allow a user to submit Application. Set required params to Allowed and save the configuration.
Creator is a required parameter to submit the Application (participant). So if you allow submission of application forms by unregistered users then you have to set a user who will be the default creator for this applications. Proceed to Site Administrator > Components > NorrCompetition > Options and click on Competition tab and find Application Creator parameter. Select user whom guest applications (participants) will be assigned to. For example it might be any Super Administrator or custom user. Please note that this user will be excluded from AUP integration and will not receive notifications about applications/participants.
Below you will see Captcha parameter:
Enable this parameter if you wish to.
If you are re allowing guests to submit applications, it is highly recommended to enable captcha. NorrCompetition uses core Joomla plugin. Go to Administrator Panel > Extensions > Plugins and edit Captcha - ReCaptcha plugin. See official tutorial: How do you use Recaptcha in Joomla?
Finally we will get something like this:
You can override permissions in specific competition. It might be useful if you need to allow or deny submission in some selected competitions. Proceed to competition edit mode, click on Permissions tab and override settings.
