How can I remove my avatar and add a picture where the avatar is now?  Thanks!

Look in the FAQs above....it tells you how to do it.

I want to change mine as well. I clicked "contact us", and it just went to my e-mail's home page.  

Go to your profile then click edit profile then click change avatar you will have to have administrator place your new photo by e-mailing them/him make sure you crop and re size to 100 x100 as they had patience with me as I had to do it twice. Shedrock I believe that is when you have to e-mail them your new avatar cropped and resize. Correct me if I am incorrect but I believe that is how you would do it. I am one of those dinosaurs and took a while to even get the photo bucket down and never have text ed or go on the net from my phone as my phone does not even have a camera. I know this topic should go over to the photo section but just trying to help brother.

Pat hit the nail right on the head FAQ tells you how.
