Hello
I will reply from last questions
4. Is there any way to subscribe to content from specific categories?
In
Simple Membership - component for Joomla Users manage You cab create so many Subscribe groups as you wish. These Users groups may be free or Pro.
There you select to which Joomla User group - user will approved after registration.
Next when you in another Joomla component create some content. In most case - you may set: who can access to this content.
If we say about "Joomla articles", in Every "category for Joomla article" and in every article you see param "Access", so there you set who can access to this article.
Connect Joomla User groups with "Access" or create new access you may in joomla admin->Users->Access level
3. Is there a way to display the users profile picture next to the welcome message when they are logged in?
If you say about "Greeting" section in login module - NO, we haven so settings
But in Login module you have settings "Redirect after login". So you may create menu to user profile, and n it show user photo. And redirect user, after login, to self profile
2. How can I disable the 'extend the registration' link in the display panel?
Sorry, now we haven't so settings
1. Is this non-expiring by default?
No, non-expiring, but you may hide this "user group" with help component settings, and show only "expiring User groups"
