Registering Your Avatar at Gravatar.com

Actually this may first time to heard about this avatar thing though im on my 8 months on blogsphere,lol anyways thanks to my friend whom noticed me that i wasn’t have any signature photo on my comment to his blog and i asked him, whats that, and he replied me with lol because its been¬† a several months of blogging then since now i doesn’t know this,lol but he said that i can have my avatar on gravatar.com so that i immediately checked on it, but when about to sign up, its says that i have to wait for their confirmation about my application that they will send on my email address, i even searched on youtube by the way and i found out some tutorial videos hows its work..
