I haven't changed mine in the nearly eight months I've been here, if only because the custom avatar sizes aren't really compatible with the custom avatar I'd use (see my ESPN.com profile [http://sportsnation.espn.go.com/fans/monsterdog5] for a grossly distorted, oversized version of the flag.)
The flag is from an old NationStates nation of mine called Wolfsreich and has become my rallying banner for any endeavor where a custom national flag is called for.
