landonf in list of assignees

[Ryan Schmidt]

landonf isn't in the list of people to whom I can assign tickets in  
Trac. Can he be added please, since he does maintain several ports?

How is that list in Trac kept up to date anyway? Do we have a script  
that routinely goes through portfiles to look at the maintainer field  
and see who should be added to or removed from the list in Trac? If  
not, should we have such a script?
