Can I suggest the 'greeters page' needs to list what languages people speak (preferably in the language!) and what time zones they're in. If I have a dead n900 ("help! I bricked it!") I don't want to PM a greeter who says they speak English only to find they'll be asleep for the next 12 hours. It might even be in 'wiki' format, so individuals can put up if they're going to be aftk for a week.
