Hello,
I'm not sure if you can move the 'Title' box to the first tab of the registration forum. I have not seen that been done before. But as for changing the name of the 'Title' field, you can change the name of the field by following the below steps:
1. With the admin user of Portal, navigate to the following URL:
<portalhostname>.com/admin?action=list&path=/xml_content/phrasepacks/v3
2. For the dashboard-display.xml, edit the text of that specific .xml (yellow pencil icon)
3. Look for the below two option keys:
<Option key="title">Title</Option>
<Option key="description">Description</Option>
4. DO NOT change the Option Key itself, leave them as title and description, but you can edit the contents within it. Example below:
<Option key="title">Change This To Whatever You'd Like</Option>
<Option key="description">Change This To Whatever You'd Like</Option>
5. Hit Save at the top right
6. Once back to the CMS, you will have to publish the page you just edited. A green arrow icon should've appeared, titled 'Publish'. Once you click that, the changes should take effect.
I hope this helps!
