You could achieve this with [SSO](https://muut.com/docs/administration.html#sso) by setting your own default avatar for users who have not created one yet.
I'm using wix to host your forum. Is there a way to take advantage of the SSO features with wix? Meaning I don't have the ability to change the coding...thanks!
Ah that's right. I feel like I knew that already about your forum. Unfortunately I don't believe it's possible to use SSO with Wix at the moment.
I just learned that [Wix has a forum thread](http://www.wix.com/support/forum/html5/wix-app-market/wixlab-apps/wishlist-moot-forum-feature-re) dedicated to Muut feature requests. I see SSO support is already on there but it certainly won't hurt to request it again.
Thanks Michael! I'll post my wix questions on the forum. Appreciate your help :)
Do you have a live example of a Muut community using this modification?
