OK, so installing the FCKeditor (see part 1) was quite fiddly. I've now installed a couple more add-on modules, and they were pretty easy to do.
Taxonomy Menu - I'm hoping to be able to list key words for research topics as a menu or tag cloud. Not had time to play with this.
Backup and Migrate - After yeaterday's database corruption, I made a backup of the database via PHPmyAdmin. I figured it would be nice to be able to do this from within Drupal, so I installed this module. Seems to work pretty well, though I don't think it compares too well with Joomlapack, the backup system I use in Joomla, which allows you to make complete site backups (both database and files), and to do this in a way that the package includes an installer. I bet there's a comparable module out there for Drupal - it's just a matter of finding it...
