Hi Johnny_boy,
Thanks for your comment, and indeed you should be able to use your own avatar / picture. For some reason it was set to allow this only after posting so many messages. I have changed that now and you should all be able to upload your own picture if you want to (remember to edit it in a graphic package to resize it to a 50x50 pixel gif or jpg). Simply click on "user cp" above, and then on edit options, scroll down to "change avatar", and on the next page got to the very bottom: "Custom avatars" and follow the instructions.
The choice of current avatars is indeed "original"

, though I am in the process of uploading further choices (Mr Men and Little Miss).
Cheers,
Franck.
