There is no way to add an avatar for forum

There is no way to add an avatar for registering admin on the site and forum. When registering as a developer, there is such an opportunity. Perhaps this is done on purpose.

Hello Adm,

We use Gravatar as provider.

Regards

Why we use gravatar in Akaunting software for users. How can we change it. It is disable once clicked on gravatar on. I can't change it. and there is just blank. and no image why? It's broken on name on user list?
