How can i set the login message?

In detailled Site near bottom u get a message "You have to login to assign to this event" .
I would like insert a link to the login site. How can we do that?


And maybe you cen help me with this disformatted list elements you can see at the picture?

with ftp you open the event/tmpl/default_attendees.php and search for:
case2:
echo JText::_('COM_JEM_LOGIN_FOR_REGISTER');
and replace it with:
?>
<input class="btn btn-primary btn-sm" type="button" value="<?php echo JText::_('COM_JEM_LOGIN_FOR_REGISTER'); ?>" onClick="window.location='/index.php?option=com_comprofiler&view=login';"/>

or similar, (I am using CommunityBuilder Login)

for the disformatted elements, german words are too long, if you find shorter words, it will be ok

Ok thats see good. But can u explain the complete url for make these changes?
components/com_jem/??? ?

best is: you disable temporarely the searchfriendly URL in the configuration. Then you go to your login page and take the url you see in the browser. Inside of your joomla! you can use the address from index.php...
you insert it.
Don't forget to enable the searchfriendly URL in the configuration

Ok i mean where can i found the file :/default_attendees.php ?
I cant found that on /components/com_jem/

-->components/com_jem/views/event/tmpl/default_attendees.php
