I have 6 Garth avatars now and I am going to keep changing mine or ever and ever or as long as there is an AB and I am a member of it and my laptop works and i have an internet connection and can still type
beats me, I am happy with my photo and get no kick out of fiddling with Gravatar. I might occasionally change it to mark the anniversary of Agincourt, but probably not.
I have changed mine a few times. Sometimes it is to be topical. I had the Bobby Moore 1966 World Cup Gromit. When we were knocked out, I changed to the Dutch Gromit.
I have dabbled with the AOG John Bull Gromit as a joke. I have also had the Winston Churchill Gromit and the back of a £20 note Gromit.
It is not difficult to do, it harms no one and variety is the spice of life.
