I have a list in SharePoint 2007 with a Person or Group type column, named "Attendees" which can contain multiple persons. I want to update Attendees with the logged-in user name on click of a custom link on the form which I have inserted. I was thinking of triggering a workflow which will update the list item, but am not sure how to trigger the update workflow. I am not using nay coding but only SharePoint Designer. Any leads or help would be appreciated.
If you want to update a listitem or start a workflow without server side code, then in SP2007 you only option is to use the Web Services.
