Avatars need to be ok'ed by a mod so if you changed it recently it just might not have been looked at yet. Not sure about the sig what problems are you having...?

i just saw ur request for avatar approval, but there wasnt anything to approve. if it works right it will show up in ur profile, but you wont see it in a post until i approve it.
so make sure u are meeting the standards we have set for them... let me know if u need any help.
