Help: Avatar Not Showing In Posts

I am a forum member for some time now. I put up an avatar in my profile, too, but it is never showing in my posts. Any idea why that may be?

Are you sure it's the correct size, 80 pxl x 80 pxl and 72 pdi?

OK, fixed ... I thought I had the avatar done, but it was the profile picture :-/
Thanks for the help, put me on the right path!

noob question: Are the avatar and signature options available to junior members, or do these become available only once a certain number of posts/experience is accrued?

Please ignore the above -- true to my noob status, I hadn't found where to set the avatar and sig!
