The Padalecki Project
In 2006 and 2007, madam_rosmerta started The Padalecki (Birthday) Project, a scrapbook project for Jared's birthday. Fans were invited to contribute pages for the scrapbook, wishing Jared all the best for his birthday in June.
In its first run, madam_rosmerta also starts sub-projects like the soundtrack project called "Jared Jives" as well as the charity project "Paws for a Cause", supporting the organisation "British Columbia Society for the Prevention of Cruelty to Animals." (Source)
In 2007, fans were also invited to send in their videos, so a DVD could be made. 95 scrapbook entries were received. (Source)
Similar projects were iniatiated for Jensen's birthday and in 2007, also for Eric Kripke's birthday, but The Padalecki Project seemed to be the most recognized, probably because of the fact that it ran under a title.
