Football is a global game - and that's also true of Charlton's supporters, with the Addicks' fanbase stretching right the way around the world.
Charlton supporters' clubs exist from as near as Greenwich and Bexley to as far afield as Sweden, Denmark, Canada and New Zealand.
And with the internet constantly making it easier for fans to get in contact with one another, supporting Charlton is now a global community.
An illustration of Charlton's international support was evident in July 2008 when Cam Seed, the nephew of the club's legendary manager, Jimmy Seed, travelled to The Valley from his home in Canada to have a tour around the stadium.
And Moira Bartram, daughter of Charlton's highest appearance-maker, goalkeeper Sam, is another regular visitor from the same country.
A new fans' forum to discuss Charlton issues with senior club officials was launched in 2008 and overseas supporters are represented by organised groups in Sweden and Australia/New Zealand.
Australia/New Zealand: (Terry Hastings) - firstname.lastname@example.org.
Sweden: (Lars Liljegren) - email@example.com.

The club's video channel allows subscribers to view a variety of content, as well as listen to online match commentary of every Charlton game - home and away - via the Addicks' official radio partners, BBC LONDON 94.9.
