I have a confluence page with a table and I want users, who wants to subscribe to an event, to put their names into the table. Unfortunatly, as there are many users, there are always editing conflicts. So I wonder, can I write a user macro (or a plugin), that just renders a subscribe-button to a page and when someone clicks on this button, a new table-row with his/her name is attached to the page?
The user macros, I have found so far are all about viewing and displaying various content, but not about creating. Can someone help?
Thanks,
