In 1.9, database activity entries could be uploaded via the 'Add entry' tab. In 2.0 the feature has moved to a separate page mod/data/import.php

How about the following help string for 'Upload entries from a file':

$string['uploadrecords_help'] = 'Entries may be uploaded via text file. The format of the file should be as follows:

• Each line of the file contains one record
• Each record is a series of data separated by commas (or other delimiters)
• The first record contains a list of fieldnames defining the format of the rest of the file

The field enclosure is a character that surrounds each field in each record. It can normally be left unset.';

$string['uploadrecords_link'] = 'mod/data/import';

Also, just wondering whether the import and export links in the settings block could be changed to 'Import entries' and 'Export entries' to match the glossary.
