I’ll list the whole process, even though you seem to know how to get where you need to be…
Go to “Your Account” and select “Change Info” or just click .
Scroll all the way down to the bottom of the form and click “Upload through forum profile”. You will get the attention message you mentioned. Click “Continue”.
Scroll to the bottom and click the browse button after “Upload Avatar from your mathine”. Find your avatar file and then select “Submit”.
If the file is too big, you “should” be getting a message telling you that, but I see that it just goes back to the attention message. Make sure the file fits the size and diminsions limits.
If the file size, etc. is ok, and you still can’t upload. PM me and we’ll get it figured out.
