Common settings when you reuse old Drupal site to make a new one

You have a  Drupal site and you want to make a replica of it so that you can build a new Drupal 6 website. The common changes you want to do is to change site name, email ids etc. But here is the full list.  Here are the common steps that I do to quickly create a new one.
This saves lot of time!

When you use taxonomy_menu and Menu Block modules

Whenever you use these two to show category list then don't forget to check on the menus created in admin/build/menu-customize/menuname... If your vocabulary and its terms don't appear then in the particular menu(created using menu block) check on all the terms. This is the common thing I forget when I create a new vocabulary.

Change Site-infomation

Go to admin/settings/site-information and change the required settings

Change webform settings

Go to admin/settings/webform and change the settings

Add/modify sites in the admin/settings/nofollowlist

Check triggers set

Check for set triggers. Normally I set send email whenever a comment is added in the site so that I can go and approve the comment. Go to : /admin/build/trigger/comment

Check Actions

Along with triggers check the set actions at : admin/settings/actions. If any action is set then you'll see trigger hyperlink. Click it to edit it. You'll get an url like: /admin/settings/actions/configure/1

Edit Rules

Change Rules at /admin/rules and edit it as per your requirement

Edit Webform Content

Go to /admin/content/webform and change the content settings

Disable Performance caching mode

While in development system disable admin/settings/performance so that your edits immediately take affect while you develop your site otherwise you may find stale content when editing which will simply puzzle you.

Update the site privacy policy

Update the privacy policy from here, check on all the advertisers so that you are all done if you ever show their ads on your site.

Update site offline message

Update the message at : admin/settings/site-maintenance

Change the logo of site

Add Adsense Code

At least create a new Adsense search and feed the slot number at build/block/configure/adsense_cse/0

Change Footer Copyright block

Go to /admin/build/block/configure/block/ and change the copyright statement etc.

User Account Creation

Check if users are allowed to create accounts
