Quote by anaisavatar pics don't have to be approved...
Which begs the question why it was deleted then, as it's been there all this time - in fact, in order for it to have been uploaded in the first place, it had to be approved by someone, somewhere:
I know Anais, I'm referring to it on my profile where it has been for a very long time and where it was deleted from in the last 24 hours. However, I've sent Admin a message regarding this as I had always thought you could keep your avatar in your pictures (as mine was) - and with the advent of groups now, I've expressed the opinion that these ought to be the exception anyway.
If there's a way for peoples avatars to automatically show in the group members list rather than having to use a picture of yourself, that would seems a sensible idea to me. Especially when forum users are more recognisable by their avatar than anything else. Whether this can be done though, I don't know.
