Sure
When you go to the buddy list section of your profile, you see two columns of white boxes. The first is your buddy list, and the other is for people you want to ignore on the site.
On your buddy list, you type in the names, one per box, of who want to add. If you want to get rid of someone, just remove their name from the box and then click update buddy list. When you do this, the page should reload and your list should now be updated with the name(s) of the member(s) you've removed.
Let me know if it doesn't work for you for some reason!

Also some members with firefox may be having problems with the profile pictures, it is most likely because of Norton, or a similiar program or firewall on your computer that is blocking the image. However, if you are having this problem please post here and let me know if you're running Norton or some other program or firewall.
