Ok, I have been trying to change my profile picture, and even tho it tells me that my new pic is my new profile pic, my old one keeps coming up on my posts. What am I doing wrong?

Duh, never mind, I had a brain fart. I was changing my profile pic, and what I wanted to change was my avatar. Its been a long day.

I want to make my profile my Avatar-how do I do this? (make Avatar pic) Can't find how to for this.

How do I set signatures, avatars and profile pictures?

You can set and change your signature, avatar and profile picture in the User Control Panel (providing the administrator has made these options available).
For signatures, click on 'Edit Signature' under the 'Settings and Options' area of the navigation bar within the User CP.
To select an existing or upload a new avatar, click on 'Edit Avatar'.
To upload a profile picture, click on 'Edit Profile Picture' in the 'Your Profile' section.

You may need to resize your photo for it to be accepted.
