Category talk:Absent users

Absent Template error
Hey all, I tried to add some code to the Absent template so that when it was added to a userpage it would automatically add that user to this category, but it doesn't seem to be working, I used the same code as Template:Stub and just changed the category input. I added one user manually to see if adding to the page would start up the auto-additions but it didn't work. Does anyone know how to fix it?  The T h i e f  13:06, September 21, 2010 (UTC)
