<li>set the headers and footers for mailings
<li>set the message template for mailings
<li>setup custom fieldsets and data fields. Before you do this, learn about Option Groups
<li>map import data to fields, groups, tags. Also do a large amount of data wrangling (normalization; and ETL) to get source data in a format suitable for use with CiviCRM. The data that I have is "composite" because it has individuals embedded inside organization records. So I needed to extract and flatten out contact records from their organization records; plus create and maintain a simple "external ID" system to relate them after import. This means parsing, slicing and dicing, string manipulation and making corrections or formatting data a particular way. I almost installed Pentaho Data Integration (kettle) because that tool is (supposedly) built for this job. <ref>But like since version 3, Pentaho still doesn't work even at 5. The install docs are missing. The thing failed to even load, with no error.</ref>
<li>Option Groups. There are many things in CiviCRM that are already configured as "Option Groups". "Website" is one example. When adding an Organization or Contact, and you want to enter data about their website, it could be one of many types: main, work, personal, facebook, twitter, pinterest, github etc. These are defined in the option group for "website". You can modify these to suit your data and your needs. As another example, "Campaign Type" comes defined as 'Direct Mail', 'Referral Program', and 'Customer Engangement'. I added 'Marketing' so that I can do a generic (email/web) marketing campaign.
