    Hi Gail

    Sorry to be a pain but what should the log_reuse_wait_desc value be?

    Nothing

    Anything other than that and something is preventing log reuse, meaning the log may grow if the condition persists

    I have been told that that even in simple recovery mode I may still need to clear transaction logs outside of the DB backup.

    Garbage. Besides, full backups don't clear the log anyway

    I have just gone to set up a Tlog backup within the management studio itself, using the maintenance plan wizard, and when I go to select the databases to backup it displays a warning stating 'Databases with simple recovery will be excluded'.

    Yup. simple recovery = no log backups, no point in time recovery possible. If you need to be able to restore to a point in time, then you need full recovery and log backups.

    Should the Tlog actually ever fill if in simple recovery mode or is there something else I am missing?

    It can. Not due to lack of log backups of course, but there are a whole bunch of other things that can prevent log reuse.

    Maybe take a read through these: Managing Transaction Logs[/url], http://www.sqlservercentral.com/articles/Transaction+Log/72488/

    p.s. Please in future post new questions in a new thread, not one 3 years old.
