From time to time I've been going over the pligg code & know that you guys who are coding it are trying to do what you feel is good for the community.

But as a webmaster I'd really like to suggest to have this Gravatar as an option not a feature. I'm personally not familar with the stability of the services but I do know the pligg site I'm testing runs a lot quicker without going to a third party service. I'd love users to be able to just upload their own icons from their computer.
Another thing is many webmasters will use & make their own language versions of the software.

It might be my personal opinion but please don't make the software dependant on a third party service for something as simple as user icons. It would be great as an option but don't make the first & only option.
