Can I remove the "Submitted by" and the Date from content in Drupal?

It is nice to give credit where credit is due, but in some cases it just takes up space and just needs to go.  In our case we wanted to remove the Submitted by and Date\Time from our polls.  The submitter would be the same person every time, so no need to give credit.  In fact this may be good practice for all site owner\editor generated content to remove this extra query and reduce the page size\load times.

For each content type where the Submitted by is not needed, go to "structure", then to "content types."

Configure Block in Forum Topics Block

Problem: Using contextual links allows admins to have quick access to editing virtually any content on the site.  In some cases, the cacheing system can get corrupted and display the Configure Block link in the Forum Topics Block and possibly others to unauthorized users.

Not to worry, this is not a vulnerability, as the page it links to just says you are unauthorized to view this page.  It is however a nuisance and makes your site look bad.
