+
+	void MemberList()
+		- shows a list of registered members.
+		- if a subaction is not specified, lists all registered members.
+		- allows searching for members with the 'search' sub action.
+		- calls MLAll or MLSearch depending on the sub action.
+		- uses the Memberlist template with the main sub template.
+		- requires the view_mlist permission.
+		- is accessed via ?action=mlist.
+
+	void MLAll()
+		- used to display all members on a page by page basis with sorting.
+		- called from MemberList().
+		- can be passed a sort parameter, to order the display of members.
+		- calls printMemberListRows to retrieve the results of the query.
+
+	void MLSearch()
+		- used to search for members or display search results.
+		- called by MemberList().
+		- if variable 'search' is empty displays search dialog box, using the
+		  search sub template.
+		- calls printMemberListRows to retrieve the results of the query.
+
+	void printMemberListRows(resource request)
+		- retrieves results of the request passed to it
+		- puts results of request into the context for the sub template.
