Footer link

Hi All

A different question about the same site (https://leadershipskills.org.au) I mentioned a few minutes ago.

The site footer includes the text Sponsored by the Australian Leadership Development Centre, linking to our main site https://www.leadershipdevelopment.edu.au

The text and link was installed by someone who set up and customized the theme for me. However, they accidently set the link text as ‘Australian Leadership’ rather than ‘Australian Leadership Development Centre’.

Is this something I can change myself?

I have a rudimentary understanding of html etc.

Cheers
Shaun
