Post installation

I am struggling to get my head around the various modules for permission and access managment. I need a way to allow only one user and all members of Staff to access some pages.

I am trying to create a system for a company to share information with clients.

I was wondering if there is a module that can be used to allow user profiles to have avatars and comment and links or any other user customization. Similar to the one in phpBB.

"warning: mkdir(files/images3): Permission denied in /home/countrym/countrymessenger.com/html/drupal8/includes/file.inc on line 86."

I re-downloaded the image module after having my server helpdesk remove old image-created folders. Helpdesk said the folders were created by a script and owned by the Apache server, which would explain why I couldn't erase them.

But after starting from scratch, the module is looking for those folders, which now don't exist.

I have this page: http://adsoftheworld.com/aggregator with the page title news aggregator on the top. I would like to call it something else. I tried to rename it with localization, like i did successfully for other elements of the site, such as the so called random ad block title on the right side: http://adsoftheworld.com/tracker but for some reason the new title for news aggregator doesn't take effect.
