Click on the Form Designer button when in your User Account form and add the admin quota to the Display Groups, or just select 'Normal Users' so that all logged in users see the fields.
Your members should be able to modify their answers themselves as all these user fields are enabled for their quota.
If they go to their User Account form they should see them.
This is working ok on my development site, but what I will say is that my Like module revision (as yet unreleased) is more recent than yours so this may have been fixed up. We'll hopefully get it released soon.
OK - There was a typo in the GroupDiscuss item_list.tpl template. I've got that fixed up and will get it in the Marketplace but first, I'm not seeing any activity feed page not founds on my development system. Can you show me where you are seeing it on fotmd?
@strumelia - I've just looked around your site and it seems that you have changed the language strings appropriately.
Are you ok now or is there anything outstanding on this thread?
