 These are often the most contentious discussions because we're likely to ask you to show how the behavior is wrong **in general**, and not just in your particular use case. In addition, if there is a problem, we need to be able to ensure that users who have relied on the apparently faulty behavior (possibly for years) aren't going to have problems if they upgrade to a version of ADOdb that has corrected behavior. That might mean, in the short term, an optional, parameterized change. Remember, ADOdb isn't an obscure little side project, there are normally 100-200 downloads per week, continually over a period of nearly 20 years.
 === You want to enhance the functionality of a specific function ===
-Say, for example, you wanted to add the ability of the **mysqli** connector to use
+Say, for example, you wanted to add the ability of the **mysqli** connector to use SSL connections to connect to the database.
+  - Start first by seeing how you can use the existing methods to provide access into your new codes. Don't, for example, modify the format of the **connect** function to require new, or modified parameters.
+  - You might, for example, use the **setConnectionParameter** method to inject the SSL parameters into the connection.
+  - If you need to add new class variables or methods, make sure the connection doesn't fail if they are not set.
+  - Make sure that your feature doesn't interfere with existing configurations.
+=== Adding A New Feature ===
+You might decide to offer a new method //**year**//, that provides a database independent method of obtaining a 4 digit year from a date field. If you use MySQL, then you might recognize the correct syntax as
+<code sql>
+SELECT DATE_FORMAT(field,'%Y');
+</code>
+You would then add the code into the drivers/adodb-mysql.inc.php file in a function like this
+<code php>
+/**
+* Formats the date into year only format YYYY
+*
+* @param	str		$field	The name of the date to format
+*
+* @return	str		The SQL text
+*/
+public function year($fld)
+{
+    $x = "DATE_FORMAT($fld,'%Y')";
+    return $x;
+}
+</code>
+In order to fulfill the requirement for cross database compatibility, you should research the method of obtaining the same information from at least other Tier 1 databases. You would find that you would need to add code like this
+<code sql>
+SELECT YEAR(field) //mssqlnative, mssql drivers
+SELECT TO_CHAR(field,'YYYY') // oci8 drivers, postgres drivers
+</code>
+Even if you cannot test these yourself because you have no access to the database, you can code them into your branch and put out a call on the issues page for help testing.

+You need also to create some end user documentation, that can be used as a basis for docuwiki pages.
