[Plugin: DMSGuestbook] About gravatar email address

I find it really a great and successful plugin. Thank you!

There’s just one issue that I feel could be improved which is mentioned here before.

I really hope to see people’s gravatar without troubling them to type email twice. Could you or anyone tell me how to hack the source code for that?

Thanks a lot.
