I love the plugin, especially in conjunction with Default Gravatar Sans as that finally removes ALL Gravatar calls from the site whether has one or not. Brilliant work.
I am only worried to let users upload files to my server as many file formats can be hidden as ie a jpg file and then the site is hacked in no time so I had an idea and maybe you like it:
Is it possible to store the uploaded pictures to an entirely different server that ONLY stores those avatars or maybe even to something as simple as a Dropbox Account?
Love to hear what you think!
