Editing the - Welcome to our community banner

Hi There,
Just wanted to know if anyone out there knows how or if you can change the text on the homepage banner that shows the rolling banners, with the text Welcome to our Community. Have added loads og great images in the rolling banner, but now would like to amend the text to something more appropraite to my site.  Just wondered if it could be done, and if so, how??? Any help much appreciated.
Many thanks,
Sean
