How can I insert a hyperlink into the Screen Messages (Top Instructions)?

Go to the Settings tab | Screen Messages sub-tab OR the Signup Sheet Design tab | Instructions button.  In the Top Instructions Editor, highlight the text that you want to be the hyperlink, and then press the Edit or Add Link icon. Key or paste the link you wish to use.  You can provide a link to your own website, or press Select to upload a file (such as a PDF) to host it on ivolunteer.com.
